I'm trying to build binutils-2.39 and gcc-7.5.0 following the instruction here:
https://www.nongnu.org/avr-libc/user-manual/install_tools.html
These instructions have worked for me in the past. However with the above versions at least I get a non-working compiler. It fails like this:
$ avr-gcc test.c -o test
/home/tuser/local/avr/lib/gcc/avr/7.5.0/../../../../avr/bin/ld: cannot find -lm: No such file or directory
/home/tuser/local/avr/lib/gcc/avr/7.5.0/../../../../avr/bin/ld: cannot find -lc: No such file or directory
I haven't had much luck with google for these errors. Ideas?
It looks like my mistake was expecting the link step of compilation to work before avr-libc was installed. The above "cannot find" messages apparently refer to components normally provided by avr-libc.
Since the compile and link of a simple test file didn't work, I didn't think building avr-libc would either. But it did, and after installation
then building of the original (basically empty) test program did also.
This probably should have been obvious but something pathological in my normal (non-test user) setup is causing the ./configure of avr-libc to fail in a way that let me astray. Sorry if this cost anyone any time.

On a Windows system, currently I'm trying a waf configure on a directory of code, and it spits out the error "could not configure a C compiler."
Now, I'm 100% certain that I have gcc and g++ installed and in my path because when I type gcc --version, it gives me the current version information. (I'm using mingw and the gcc/g++ are in the /bin subdirectory).
In the author's code directory there is a wscript file which looks like
C_COMPILER = 'gcc-4.7'
CPLUSPLUS_COMPILER = 'g++-4.7'
Now, I have tried changing the strings to simply gcc as well as gcc-4.8.1 (since my current version is 4.8.1), but it still says could not configure compiler.
I tried reading one solution on this same site that looks related, but the solution was on ubuntu and trying to work through those commands didn't help
could not configure a c compiler
I'm at the end of my common sense here after making sure I have gcc and g++ installed, trying different strings in the wscript file trying to get it to recognize I have them installed, and could use some help, thanks.
Edit: I've now tried simply deleting the lines in the wscript file where it changes the compiler name, and suddenly waf configure goes through, but the waf build fails saying things like it can't find really basic things like include vector. The output says it's defaulting to msvs (microsoft visual studio) whereas the author says gcc/g++ is needed; maybe this is the issue but how do I get waf configure/build to use g++/gcc as default?
Any help on my problem is appreciated...
I'm trying to run this program located in the sparsenet.tar.gz file at http://redwood.berkeley.edu/bruno/sparsenet/
There is a README that I try to follow but I can't seem to compile my cgf.c...
The first step I assume I did correctly (I'm pretty sure I am able to compile the libnrfopt.a).
But when I type "make" in the sparsenet directory, it says:
new-host-2:sparsenet user123$ make
mex -I./nrf -L./nrf -lnrfopt cgf.c
make: mex: No such file or directory
make: * [cgf.mexmaci64] Error 1
I assume it means my terminal isn't recognizing Mex, can anyone point me to how that works? (Before you tell me I haven't done enough searching, I have...I just cant seem to find anything relevant...I have my command line options in Xcode running, GCC works, Mex -setup works)
By the way, I'm doing this in Terminal, not inside MATLAB. Doing it inside matlab by directly using Mex doesn't work for me either.
Also I've changed the mex extensions to a variety of choices including mexmac, mexmaci64, etc.
Thanks in advance!!
I was able to get it to work (R2012b, OS X 10.8.4). The code is old though, looking at the dates on some of the files so I'm not surprised that you had issues. Following the README, first I performed make libnrfopt.a in the nrf folder using Terminal. Then, in the Matlab command window I used cd to move to the sparsenet folder and executed (the same command that that produced an error when you ran make from the Terminal):
mex -I./nrf -L./nrf -lnrfopt cgf.c
From here I was able to follow the README and run the example.
By the way, if you've never run mex in Matlab before, you may need to run mex -setup first. As you mentioned Xcode, I assume that you have the compiler you need.
Ok I figured it out, in the makefile, I just needed to change the Mex = mex to the directory of mex.exec in my Matlab folder and change mext to maci64
Yes I did put:
MEX = /Applications/MATLAB_R2012a.app/bin/mex
MEXT = mexmaci64
In case your mex setup is not alright, check mexopts.sh file and change
to gcc-4.2 and g++-4.2 in the CC options. I had these compilers. Other compilers
should work too.

I am trying to build xmlsec on Windows... I am not an experienced C/C++ developer and not really familiar with the build process if something along the lines of "make ... make install" doesn't do the trick.
xmlsec comes with a Win32 subdirectory, a nice ECMAScript configure.js that takes an optional bunch of parameters and a readme which explains that after running the configure, "nmake ... nmake install" should do the trick. (Obviously it isn't quite that easy or I wouldn't be posting here!)
xmlsec also depends on a number of other libraries (see here for a graphic). I have downloaded the sources for those libraries.
My problem is that I don't know how to arrange those sources, or what to tell the configure.js script, in order to get a build to work.
For instance, the nmake process complains that it can't find "iconv.h" (iconv is one of the required libraries), which is not surprising because there isn't one. Instead there is an "iconv.h.in" and an "iconv.h.build.in"... which I don't know what to do with to produce the required 'iconv.h".
(I am using MS Visual Studio 2010 at the command prompt (which I think is the recommended approach.)
Does anybody out there know how to do this? Any help at all would be very much appreciated.
TIA
Mike Peat
You don't need to build xmlsec, you can directly download the wheel file from this link
https://github.com/mehcode/python-xmlsec/releases
It has all the dependencies installed with it.
have you tried the Msys with Mingw32 compiler? In Msys, you can do make and make install trick. I have successful with Msys in compile xmlsec. If you want to use Msys and have difficulties, I can help.
Anyway, in general, there must be a iconv.h file in the pre-compile folder provided by Zlatkovic (i.e C:\iconv\include\iconv.h). You may want to download again the folder. After figure out where all the dependencies are, put the path in environment path. For your information, I once tried with the configure.js but not successful. Hope that you are luckier than me :D
Hi Kristine (#Kristine T) - (and thanks for getting back to me!)
I had not been doing "make clean", but have now done so ("make clean", followed by "make" - no change in the result though).
The problem I get with the "make" is that it throws an error on compiling "dl.c" saying that "PACKAGE" is undefined (line 295).
I have also had problems using the compiled version of libxml2 - "configure" always says it can't find it (it is there, but...), so I have been using the --with-libxml-src=... parameter to configure, giving it the full source of libxml2 to work with, getting configure to at least finish OK.
I don't have the same problems with openssl or libxslt where I can either tell configure about the compiled version (using --with-XXX={path-to-dir}, or just omit ={path} bit, in which case it seems to find MinGW's own versions, but that doesn't work with libxml2.

I'm trying to build a cross-compiler (x86->64) on my windows system, with the aim of targetting windows 64, however my software currently relies on open source libraries which also have open source dependencies for which there are no prebuilt binaries available with which I can compile. This means that if I want the 64 bit versions I need to compile them.
I've installed MSYS and mingw, I'm also in the process of adding mingw-w64 to the mix so that I can finally compile the libraries in 64 bit form for use with my software. I'm following the steps as closely as I can using these instructions and in the order listed on that page, I'm currently at the step titled "Building the GCC core cross-compiler(s)", but when I try to compile with the line:
$ ../gcc-4.6.1/configure --target=x86_64-w64-mingw32 --enable-targets=all && make -j 6 all-gcc && make -j 6 install-gcc
I get the output pasted here. I should note that I of course snipped the previously executed commands and that last command was the last one listed before all the errors were displayed. Also, I have no idea if it's the cause of all the errors due to the '-j 6' argument, but everything prior to it at least looked successful.
What's the problem and how can I fix it?
Oh, in anticipation of one potential suggestion; no I can't just switch to cygwin.
Edit: Okay after executing them individually, here's the output of the configure command, the output produced by make all-gcc (no -j argument), and config.log. Note, I didn't run a make clean beforehand which may explain the different ending, I didn't do it in the interest of time to write this update, but I suppose I'll just make a different compile folder and re-execute it cleanly to hopefully see the same error as before while I wait for a response.
Edit 2: The make all-gcc failed again as expected, this time the output should help a little more I hope.
Thanks very much for your help.
Your config.log shows that the build process will use the binaries in x86_64-w64-mingw32/bin for stuff like ar, as etc... These are for internal compiler use only, and they should all be available in your /mingw/bin directory. I would strongly suggest asking on the mingw-w64-public mailing list for help.
I spent the whole day setting up GCC as per
http://cygwin.wikia.com/wiki/How_to_install_GCC_4.3.0
On the gcc make step, it told me it needed a c++ compiler to continue for whatever reason,
So I updated Cygwin in the usual fashion and got gcc-c++.
After that, cgywin did me the courtesy of deleting the 3 prereq libraries that I had installed previously,
So I went about remaking them. GMP worked fine, and then I got to MPFR. For whatever reason MPFR is throwing this error:
configure: error: libgmp not found or uses a different ABI.
The resources mention this error here.
I’m pretty sure its finding GMP alright as cygcheck shows it up no problem, and the config even mentions it finds it.
When I try:
./configure --with-gmp-build=/gmp/,
it throws:
error: header files gmp-impl.h and longlong.h not found
So far I have not been able to get MPFR working, despite googling and trying for hours.
MPC also fails to find GMP in the usual manner.
I've also tried just handing the libraries to GCC in a subdirectory and letting it compile them.
When I try that, it gets to the make step, then throws a stage1-bubble error and fails. No description of the error or anything.
I have no idea what else to try.
After compiling and installing gmp, I had the same problem building mpfr until I set correctly the library search path:
export LD_LIBRARY_PATH=/usr/local/lib
export LIBRARY_PATH=/usr/local/lib
export CPATH=/usr/local/include
as it is explained in the http://cygwin.wikia.com/wiki/How_to_install_GCC_4.3.0
Instead of this:
./configure --with-gmp-build=/gmp/
USE THIS:
./configure --with-gmp-build=/gmp
It doesn't like having the "/" at the end.
I know this post is a bit dated, but I was looking for an answer or results to a similar situation but with much more current versions of the same libraries. While reading this post as for some suggestions as well as other online material I was able to piece everything together. So for anyone who may be working with the newest releases here it goes:
First you will probably want to configure, make and install GMP first for both C and C++ as static libs; also make note of the architecture x86 or x64. Once you run make, make check, make install; and you are confidant that you have no errors, then when you go to configure MPFR you will want to run it as such:
./configure --with-gmp-build=/path/to/gmp --enable-static --disable-shared
and if the paths are set properly this should give you the needed generated make file.
I'm brand new to Unix-Posix environments and commands and new to Cygwin. I've mostly used Windows platforms and very few Macs or Apples. Matter of fact I've only been working at this for a little less than a week as I'm trying to do the same thing. So now I'm venturing into a whole new world of Unix... but it's sort of simulated through Cygwin as I'm still running windows.
I'm trying to build GMP, MPIR, MPFR & MPFRC++ all from the latest original distributions and eventually will try to integrate them into Visual Studio 2017.
I had actually found this post because I was able to build MPIR through visual studio with the help of python and vyasm, but as for GMP I needed Cygwin with GCC. It took me a little while to figure out how to get GMP to build properly but once I did and ran the tests I was able to have all pass with 0 failures. I then started to work with MPFR the same as you.
My similar issue was after I ran ./configure as default, it was giving me the message that the libgmp wasn't found. Also if I tried to call make, it would do nothing as the make file didn't exist. This led me back to doing google searches... While searching for tips, suggestions etc. I came across this Q/A. While I was reading this Q/A, the install files, some other FAQ and even another website, I was kind of able to piece everything together and what I have found that works is what I suggested above.
Not only do you need to set the flag --with-gmp-build but you also need to set the appropriate library types that gmp was built as and you need to make sure that the architecture types match too. They need to have the same matching ABIs.
Ah, just as I was about to finish up typing this answer, make check just finished running through Cygwin and I have a result of:
Testsuite summary for MPFR 4.0.1
============================================================================
# TOTAL: 180
# PASS: 180
# SKIP: 0
# XFAIL: 0
# FAIL: 0
# XPASS: 0
# ERROR: 0
============================================================================
I hope this helps you out. The only thing is for myself; I'll have to go back and probably run all of this again from the beginning including GMP only because I believe I only did GCC and not G++ and my next step is to try and build MPFRC++.
Then I might try to do some related libraries from here afterwards. My first phase is to try to build them all through Cygwin and GCC/G++. The next step will be to try and port them over to Visual Studio 2017.
You might want to use --with-gmp-lib=/path/to/gmp/lib/dir
