'rbenv install 2.0.0-p247' fails - ruby

i already discussed this issue with the maintainer of ruby-build and followed his advice by googling for similar errors. i found similar ones but they do not seem to match my specific problem:
i'm trying to install ruby with rbenv install 2.0.0-p247 (using the ruby-build plugin) on archlinux – but the command fails.
here the last 10 log lines:
rbconfig.rb updated
generating enc.mk
compiling dln.c

generating prelude.c
compiling prelude.c
linking static-library libruby-static.a
verifying static-library libruby-static.a
collect2: error: ld returned 1 exit status
make: *** [libruby-static.a] Error 1
i would appreciate any hints on this problem – thanks!

To find out what's wrong here, the best bet is to run the Ruby installation yourself to see exactly what's amiss. ruby-build typically downloads and extracts Ruby in /tmp (it should be the same path where it also saves the log file of the failed install).
Go to that directory and run:
$ ./configure
$ make
To see if you get the same error. If you do, then try to re-run the command that failed again. In your case this is probably:
$ ranlib libruby-static.a
To see why it fails.

Compiling Elmer FEM on macOS Mojave causes the fatal error: 'string.h' file not found

I'm trying to follow these instructions to compile Elmer FEM on macOS Mojave Version 10.14.6. However, when running the make install I get the error message:
.../elmerfem/umfpack/src/umfpack/include/umf_internal.h:29:10: fatal error: 'string.h' file not found
#include <string.h>
^~~~~~~~~~

make[1]: *** [umfpack/src/umfpack/CMakeFiles/umfpack.dir/all] Error 2

searching the internet this post suggests
xcode-select --install
sudo xcode-select --switch /Library/Developer/CommandLineTools/
which had already been done before in my case and have no effect on the above error. This and this post suggest
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / -allowUntrusted
which leads to the error message
installer: The install failed (The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.)
I would appreciate it if you could help me know what is the problem and how I can resolve it. Thanks for your kind support in advance.
P.S.1. As was asked here, my make version is GNU Make 3.81.
P.S.2. the list of string.h files on my hard drive here.
P.S.3. the output of CMake is pasted here.
OK, I think I solved the problem. From here, I ran
cmake -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ ..
while being inside the build folder. and then make . worked fine except some warning. I'm still not sure what was the problem or if this is the optimal/canonical solution. So I will not mark this as the accepted solution until others provide better ones.
P.S.1. I sent a pull request here on Elmer's HomeBrew formula as well.
P.S.2. To compile with OpenMP and MPI:
cmake -DCMAKE_C_COMPILER=/usr/local/Cellar/gcc/9.2.0_3/bin/gcc-9 -DCMAKE_CXX_COMPILER=/usr/local/Cellar/gcc/9.2.0_3/bin/g++-9 -DWITH_Mumps=FALSE -DWITH_MPI=TRUE -DWITH_OpenMP=TRUE -DWITH_MKL=FALSE -DWITH_ELMERGUI=TRUE -DWITH_ELMERPOST=FALSE -DWITH_ELMERGUITESTER=FALSE ..
I have GNU GCC and OpenMPI installed via HomeBrew brew install gcc open-mpi.
P.S.3. If you want the ElmerGUI also installed:
install qt4 with brew install cartr/qt4/qt#4 from here
install qwt with brew install cartr/qt4/qwt-qt4
then cmake -DCMAKE_C_COMPILER=/usr/local/Cellar/gcc/9.2.0_3/bin/gcc-9 -DCMAKE_CXX_COMPILER=/usr/local/Cellar/gcc/9.2.0_3/bin/g++-9 -DWITH_Mumps=FALSE -DWITH_MPI=TRUE -DWITH_OpenMP=TRUE -DWITH_MKL=FALSE -DWITH_ELMERGUI=TRUE -DWITH_ELMERPOST=TRUE -DWITH_ELMERGUITESTER=TRUE -DQWT_INCLUDE_DIR=/usr/local/Cellar/qwt-qt4/6.1.3_1/lib/qwt.framework/Versions/6/Headers/ ..

Using mingw-w64 and ./configure --host=i686-w64-mingw32.static, make fails and Makefile CC variable looks wrong

I am new to compiling.
I am trying to compile iperf3 for Windows 10 because there is no official Windows distribution of iperf3 and for the learning experience. I am trying to do so on the new Windows Subsystem for Linux feature via Bash on Ubuntu on Windows, also for the learning experience.
I installed mingw-w64, which should give me the proper compiler and environment necessary for cross-compiling:
sudo apt-get install mingw-w64
This put two directories into my /usr directory:
i686-w64-mingw32
x86_64-w64-mingw32
It also put a bunch of things that look like compilers into /usr/bin.
I unzipped the .tar.gz file from iperf3 and navigated into it. Then, I run ./configure --host=i686-w64-mingw32.static and it completes without errors.
I note that the output of the command has a worrisome line: checking for i686-w64-mingw32.static-gcc... no
I note that the Makefile's CC variable is set to gcc, which doesn't sound like the proper compiler.
Then, I run make. It fails with errors:
collect2: error: ld returned 1 exit status
make[2]: *** [iperf3] Error 1
make[2]: Leaving directory `/home/snip/iperf3/iperf-3.1.4/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/snip/iperf3/iperf-3.1.4/src'
make: *** [all-recursive] Error 1
I also see the line: libtool: warning: undefined symbols not allowed in i686-w64-mingw32.static shared libraries; building static only
I think that the ./configure is not working correctly since it appears to have not found the right compiler for my --host argument and put it in the Makefile.
What am I doing wrong?
EDIT:
I changed the command to ./configure --host=i686-w64-mingw32 per comments and it completes without error. But no makefile is created so make yields make: *** No targets specified and no makefile found. Stop.
What am I doing wrong, now?
EDIT 2:
Looks like the ./configure actually is failing. Last line of its output is nanosleep() required for timing operations., which seems to mean that its missing a library for nanosleep.
How do I get nanosleep?
mingw doesn't support nanosleep. So programs using it cannot be compiled using mingw-w64.

Install nullfs on Debian

I am using a java program. It automatically creates log files in a directory, but I am doing that myself a different way with tee. I cannot find an easy way to disable the logs, so I am resorting to using nullfs.
I cloned it with
git clone https://github.com/xrgtn/nullfs.git
and I ran
make nul1fs
as instructed. It terminates within a second, with the following output:
cc "-lfuse" nul1fs.c -o nul1fs
nul1fs.c:13:18: fatal error: fuse.h: No such file or directory
compilation terminated.
make: *** [nul1fs] Error 1
I tried apt-get source fuse and copying fuse.h into the nullfs directory, but nothing changed.
I have FUSE installed. I'm running Debian wheezy x86_64.
You need the development package of FUSE, which contains the fuse.h you're missing. Do a apt-get install libfuse-dev and it should work.
Copying the header file in the source directory did not work, because in nul1fs.c you'll notice that fuse.h is included with angle brackets. This means, the header file will be searched in the system-wide include paths. That usually means /usr/include.
Note that you then may run into this error:
$ make nul1fs
cc "-lfuse" nul1fs.c -o nul1fs
/tmp/ccbt0X7c.o: In function `main':
nul1fs.c:(.text+0x3c3): undefined reference to `fuse_main_real'
collect2: error: ld returned 1 exit status
make: *** [nul1fs] Error 1
It's a documented bug with a workaround: put the linker flags after the file lists. I.e. compile nul1fs with:
cc nul1fs.c -o nul1fs -lfuse
and not with make nul1fs, which boils down to
cc -lfuse nul1fs.c -o nul1fs

What is the issue with Ubuntu (12.10) and GCC 4.7/4.8?

Since several versions of GCC and Ubuntu I am experiencing annoying issues with paths and naming of several header and object files that are necessary for the installation of GCC.
Description: After installing ubuntu (e.g. in my case 12.04) and installing all prerequisites of the gcc, I run the following commands:
sudo mkdir /usr/local/stow/gcc-4.8.0
./configure --prefix /usr/local/stow/gcc-4.8.0
make
sudo make install
For the sake of completeness, the rest of the installation procedure:
cd /usr/local/stow
sudo stow -t /usr/local/ gcc-4.8.0
gcc -v
However, this simple and proper way of installing gcc has some issues during the 'make' step with the following error messages:
1.) The problem with 'stubs.h'
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
which can be fixed with the following commands added to ~/.bashrc:
if [ -z "$CPATH"]; then
export CPATH="/usr/include/i386-linux-gnu"
else
export CPATH=$CPATH:"/usr/include/i386-linux-gnu"
fi
2.) The problem with 'crti.o', 'crtn.o', and 'crt1.o'
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find crtn.o: No such file or directory
/usr/bin/ld: cannot find crt1.o: No such file or directory
which can be fixed with the very ugly solution:
sudo ln -s /usr/lib/i386-linux-gnu/crti.o /usr/lib/i386-linux-gnu/crtn.o /usr/lib/i386-linux-gnu/crt1.o /usr/lib
since - and I don't know why - the following commands do not solve the problem during linking steps of 'sudo make install'
if [ -z "$LIBRARY_PATH"]; then
export LIBRARY_PATH="/usr/lib/${multiarch}"
else
export LIBRARY_PATH=$LIBRARY_PATH:"/usr/lib/${multiarch}"
fi
if [ -z "$LD_LIBRARY_PATH"]; then
export LD_LIBRARY_PATH="/usr/lib/${multiarch}"
else
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/usr/lib/${multiarch}"
fi
(With these solutions I could compile GCC-4.7.2 on Ubuntu 12.04. - I have still issues compiling GCC-4.8.0 on Ubuntu 12.04, but that's different topic.)
My questions are: Does anybody know the reason/background that we have these issues? Does anybody know a proper solution? (With "proper solution" I mean a solution that does not require setting environment variables or symbolic linking libraries to different directories. To me these kind of changes are ugly, since they require changes to the system that one may not be able to trace back or redo.)
In the root folder of your GCC source execute ./contrib/download_prerequisites script.
These are the issues i encountered while compiling GCC 4.8.0 on Ubuntu 12.04 with solutions.

ERROR 1
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations. Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also
http://gcc.gnu.org/install/prerequisites.html for additional info. If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files. They may be located in separate packages.

SOLUTION
Though gcc documentation specify , that , we can provide the path of gmp
and mpfr installtion through –with-gmp and –with-mpfr flag ,
but unfortunately , i tried to give the path but it didnt work.
I am not in position to say final word about , this , whether it is a bug
in build script or something else , but bellow is the solution of the problem.
while building , add gmp and mpfr installation path in LD_LIBRARY_PATH environment
variable. Do as follows
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
If you have the libraries in different path, add the path where libraries are present

Problems linking to a library with gcc

I installed SFML from scratch today so I could work on a game. I downloaded the source, ran sudo make install, tried compiling one of my old projects, and I couldn't get it to link properly. So I tried running a simpler project: one of the samples in the tutorials. I tried to compile this one specifically, but I get these errors:
g++ -o atest test.cpp -lsfml-graphics -lsfml-window -lsfml-system /tmp/ccaa86fR.o: In function `main':
test.cpp:(.text+0x1d2): undefined reference to `gluPerspective'
collect2: ld returned 1 exit status
make: *** [test] Error 1
Trying an even simpler project, the one in the initial tutorial, I don't run into problems compiling. However, when I try to run it, I get this error:
./atest: error while loading shared libraries: libsfml-graphics.so.1.6: cannot open shared object file: No such file or directory
I checked, and the files did install to /usr/local/lib/ which is where they're supposed to go as far as I know. What am I doing wrong here?
-lGLU should fix the first error and for the second one make sure /usr/local/lib/ is in your ldconfig search path (/etc/ld.so.conf and /etc/ld.so.conf.d/* under Ubuntu) and that you ran ldconfig: sudo ldconfig -v then try running again.
