I'm trying to create a standalone of my C# app using mono's mkbundle, I got Xcode installed and the Mono Developer Kit too (I'm sure it's MDK not the runtime). Yet I run mkbundle using
mkbundle test.exe
and I get these errors
Compiling:
as -o temp.o temp.s
cc -g -o a.out -Wall temp.c `pkg-config --cflags --libs mono-2` temp.o
sh: pkg-config: command not found
temp.c:1:10: fatal error: 'mono/metadata/mono-config.h' file not found
1 error generated.
[Fail]
What's happening?
pkg-config is stored at '/Library/Frameworks/Mono.framework/Commands'.
Solution (see here and here):
Prepend the "/Library/Frameworks/Mono.framework/Commands" folder to
your PATH variable:
export PATH=/Library/Frameworks/Mono.framework/Commands:$PATH
This is needed in addition to the architecture solution proposed by aiapatag and the objective-c runtime and CoreFoundation framework solution:
export AS="as -arch i386"
export CC="cc -arch i386 -framework CoreFoundation -lobjc -liconv"
It looks like the pkg-config tool is not found. Maybe it's not in the default paths.
Do you have a 'pkgconfig' directory somewhere? It should be a subdirectory of your Mono installation.
Try to see if you have a path looking like /Library/Frameworks/Mono.framework/Versions/XXXX/lib/pkgconfig
If yes, point the PKG_CONFIG_PATH environment variable to this path, you can specify it directly when running your mkbundle command (this is just an example):
$ PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/Versions/XXXX/lib/pkgconfig mkbundle ....

I wrote a program that is using OpenSSL and I'm trying to compile it to executable for inwdows.
The command I'm using to compile is:
gcc -g -Ifolder1/include -Iopenssl/include -Ifolder2 -c folder1/lib/functions.c -o folder1/lib/functions.o
gcc -g -Ifolder1/include -Iopenssl/include -Ifolder2 -o myprog.exe main.o folder1/lib/myfiles.o folder1/lib/plus.o folder1/lib/functions.o -Lopenssl/windows/static -lcrypto
This works for linux but for windows i get
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -lcrypto
Any idea what is the corresponding flag for -lcrypto for linux?
The problem was that in path openssl/windows/static i had a library with the suffix *.lib and seems like gcc doesnt recongnize it as a library.
resolved when i change it to *.a suffix
I am trying to install a python module (SPArse Modeling Software) but the install script doesn't seem to be able to find the system's default Python.framework. This is an almost new (no migration assistant) Mac OS 10.9.5 system with both the default system python and Anaconda installed. I briefly installed Enthought Canopy but removed it when I decided to go with Anaconda. /System/Library/Frameworks/Python.framework exists and seems to have all the files you would expect.
In terminal, this is what happens:
bash-3.2$ which python
//anaconda/bin/python
bash-3.2$ cd spams-python
bash-3.2$ python setup.py build
running build
running build_py

ld: framework not found Python
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'gcc' failed with exit status 1
So, my question is, is my diagnosis of the problem correct? How can I tell GCC where Python.framework is? Is there some environment variable that isn't set correctly?
The Anaconda Python is not a Framework build of Python. If the module expects that it's not going to work. Commenting out commenting out "'-framework', 'Python'" in setup.py sounds like a good start, and if it works, then it probably is the right solution.
Compile it with gcc-5, and I successed.
This is a follow-up to the question at Element-Wise Matrix Multiplication in Rcpp
I have been getting a number of different kinds of errors with RcppArmadillo since upgrading to Mavericks. I have Xcode 5.0.2 and Command Line Tools installed. Also, gfortran from Homebrew. But I keep encountering the error below --

Thanks in advance.
Update
Following suggestions from response from Kevin and Dirk below, I re-installed Rcpp, RcppArmadillo and inline from source and updated FLIBS to point to the actual directory. This solved the issue.
# Update FLIBS in ~/.R/Makevars
FLIBS=-L/usr/local/Cellar/gfortran/4.8.2/gfortran
#Re-Install from source
install.packages(c("Rcpp","RcppArmadillo","inline"),type="source")
#Restart R
EDIT: If you're a Homebrew user, you now instead need to use brew install gcc (gfortran is no longer provided separate of gcc), and you can then follow the instructions here to get set up.
You have to symlink the libraries to /usr/local/lib manually:
ln -s /usr/local/Cellar/gfortran/4.8.2/gfortran/lib/libgfortran.* /usr/local/lib/
I thought brew link gfortran would handle this, but apparently it only symlinks the gfortran program and not the actual libraries. So, unfortunately, you have to do it yourself.
(Replace 4.8.2 with whichever version of gfortran you're using from homebrew.)
Alternatively, if you want to keep from modifying /usr/local/lib, you can use
FLIBS=-L/usr/local/Cellar/gfortran/4.8.2/gfortran
in your ~/.R/Makevars file instead, so R knows where to find the gfortran libraries.
I can only suggest you study the numerous threads on the r-sig-mac list, the different answers here on SO as well as the posts on the rcpp-devel list.
As your error comes from the failed Fortran linking, maybe also review the standard page by Simon U. as well as the tools page it points too. AFAIK you should use the (older) gfortran 4.2.* from that page with R -- but then I am not an OS X user.
Edit in late 2016: We now have more detailed instructions in section 2.16 of the Rcpp FAQ.
I can't link my program with shared library located in non-standart OSX lib directory. I've got this library from MacPorts and it's located in /opt/local/lib:
$ ls /opt/local/lib/libgmp*
/opt/local/lib/libgmp.10.dylib /opt/local/lib/libgmpxx.4.dylib
/opt/local/lib/libgmp.a /opt/local/lib/libgmpxx.a
/opt/local/lib/libgmp.dylib /opt/local/lib/libgmpxx.dylib
/opt/local/lib/libgmp.la /opt/local/lib/libgmpxx.la
I've found that one can use DYLD_FALLBACK_LIBRARY_PATH, but it not works for me:
$ DYLD_LIBRARY_PATH=/opt/local/lib gcc ab.c -lgmp
ld: library not found for -lgmp
collect2: ld returned 1 exit status
At runtime, DYLD_LIBRARY_PATH helps dynamic linker to locate libraries from non-standard directories.
In your case, you are still in compilation phase.
For gcc to know about these extra directories to search, you could use -L switch.
e.g.
gcc ab.c -L/opt/local/lib -lgmp
I have installed the latest libxml2-2.8.0, as usual: $ ./configure, $ make, $ make install.
The $ xml2-config --cflags --libs gives this output:
-I/usr/local/include/libxml2
-L/usr/local/lib -lxml2 -lm
But trying to compile any example...
$ gcc `xml2-config --cflags --libs` xmltest.c
The linker says:
/tmp/cc8ezrPl.o: In function `processNode':
xmltest.c:(.text+0x19): undefined reference to `xmlTextReaderConstName'
xmltest.c:(.text+0x38): undefined reference to `xmlTextReaderConstValue'
...etc.
Anything I've googled can be solved by xml2-config --cflags --libs flags, or upgrading to the latest version of libxml2, or something. Unfortunately, neither works for me.
What can be the steps to identify the problem?
Using Ubuntu 12.04 64-bit.
The libraries should be specified only after the source file so that the linker can resolve the undefined references in the source file. Try compiling the example with this
gcc -I/usr/local/include/libxml2 -L/usr/local/lib xmltest.c -lxml2 -lm
