I am trying to install "TAUCS" (http://www.tau.ac.il/~stoledo/taucs/) library. However, I am getting following error:
/usr/bin/ld: cannot find -lmetis
/usr/bin/ld: cannot find -lg2c
collect2: error: ld returned 1 exit status
make: [build/linux/taucs_config_tests.h] Error 1 (ignored)
obj/linux/taucs_c99_complex_test build/linux/taucs_config_tests.h
make: obj/linux/taucs_c99_complex_test: Command not found
and more errors follow.
I guess that the main error is not being able to find lg2c.
I guess I use already gcc which uses gfortran instead of g77. Where can I find g2c.a?
Searching in software manager returns me with no result. Searching in google gives me everything else other than what I am looking for.
UPDATE:
I could install g77 as described.
However, that still leaves an error:

Here is what I did to install TAUCS library
1) Download the Version 2.2 of the code, with external libraries, tgz format
wget http://www.tau.ac.il/~stoledo/taucs/2.2/taucs_full.tgz
2) Unpack it in your chosen location
mkdir taucs_full
tar xvf taucs_full.tgz -C taucs_full
cd taucs_full
3)If you didn't already do so, install libf2c2-dev (for libf2c)
sudo apt-get install libf2c2-dev
4) Remove the -Werror flag from the global compiler options file (there are going to be warnings, so it will never build if we treat them as errors)
sed -i 's/-Werror//g' config/linux.mk
5)Now run the configure script
./configure
6) Finally we need to do some command and library wrangling for the actual make
make "CC=gcc" "FC=gfortran" "LIBF77=-Wl,-Bstatic -lf2c -Wl,-Bdynamic -lgfortran"
You should get a binary executable in ./bin/linux - If you just try to run, it will give this message:
$ bin/linux/taucs_run
taucs_run: there is no matrix!

Try installing g77.
I did the following:
1) Downloaded g77 for 64 bits from here
http://www.ziddu.com/download/16792814/g77_x64_debian_and_ubuntu.tar.gz.html
You can choose 32 bits accordingly.
2) Then did the following:
tar -xzvf g77_x64_debian_and_ubuntu.tar.gz
cd g77_x64_debian_and_ubuntu
chmod +x ./install.sh
./install.sh

any sugestions or things i overlooked?
You're trying to generate and link 32-bit code (the -m32 option), but the linker can't find a 32-bit version of libgcc. The message says its is finding a 64-bit version, so the problem is probably just that you don't have 32-bit libs installed. I think on debian, you need to install the ia32-libs package for that.
I am trying to compile a plugin for my game server(more exectly this: click).
So, when I am trying to compile the plugin in my linux VM(who uses centos 7+) with make command line, I get these errors:

My question is how to avoid these errors?
Important note: the tutorial for compiling this plugin(on the main page on github for this plugin) is working for the newer versions for this plugin, but I need the R37 one.
The plugin is write in C and it has a makefile inside.
Thank you.
Install the libboost that goes with the distribution. Whatever you have in /usr/local/lib is bad.
Makefile uses -m32 compilation option for some reason causing 32 bit executable to be produced. So this executable will require 32 bit libraries. So you should either remove -m32 option or install required 32-bit dependencies.

I have installed the libsdl2-dev package for both, 32 and 64 bits.
This is the makefile out:
gcc -g -o xash -fvisibility=hidden -m32 ... -lm -lSDL2 -pthread -lX11 -ldl
I have also try to compile other projects with the flag -lSDL2 and they compile just fine.
Any clue?
Given a simple hello world code:
#include <stdio.h>
int main(void){
puts("hello");
return 0;
}
On a 64bit alpine linux installation I tried to compile it as 64bit and as 32bit.
The first works fine, but the second is missing 32bit libraries:
~ # gcc -Wall hello.c
~ # gcc -Wall -m32 hello.c

Because I found no obvious way to fix this, I fetched the 32bit version of gcc, libgcc, and musl-dev extracted to a local directory and set LIBRARY_PATH:
~ # LIBRARY_PATH=usr/lib/gcc/i586-alpine-linux-musl/5.3.0:usr/lib gcc -Wall -m32 hello.c

This partly fixed the issues, but gcc still tries the 64bit libraries first and finds tries to find the 64bit crt files.
So what is the correct way to compile a 32bit binary on alpine linux?
To make the last problem more clear, look at this:
~ # LIBRARY_PATH=/tmp gcc --verbose -Wall -m32 hello.c 2>&1|grep LIBRARY_PATH
LIBRARY_PATH=/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/:/tmp/:/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../../x86_64-alpine-linux-musl/lib/:/usr/lib/gcc/x86_64-alpine-linux-musl/5.3.0/../../../:/lib/:/usr/lib/
If I only set some LIBRARY_PATH, the compiler internally adds other directories to it. Especially it also prepends the "wrong" system directory, which contains the 64bit libraries. Therefore it uses the wrong crt libs and therefore the last error above.
I either need the correct alpine package (and not care about how it works), or I need to understand how to change that first path added internally by gcc.
According to gcc -v on alpine gcc is compiled without multilib support:
--disable-multilib
While multilib is enabled on debian:
--with-multilib-list=m32,m64,mx32 --enable-multilib
Multilib support is required for the -m32 to work reliable. Therefore the default compiler on alpine is really not suited for compiling 32bit binaries.
I'm trying to compile a C code which need SDL libraries(v1.2), SDL_draw and a library imposed by my teacher. the .c and makefile code works on an other computer.
I use a makefile and when I 'make' I get severals errors :
- first SDL_draw cannot be find although I paste it in /usr/include/2011/lib/libSDL_draw.a
- all other libraire are 'skipping incompatible' (I hope that those are just warnings)
- I though that it was compiled in static and the .so wouldn't be needed.
And I wondered what is the mysterious variable LFLMAC.
