My sysadmin recently installed a new version of GCC in / lusr / opt / gcc -4.4.3. I tested it as follows:
mike@canon:~$ cat test.c
int main(){
return 0;
}
mike@canon:~$ gcc test.c
/lusr/opt/gcc-4.4.3/libexec/gcc/i686-pc-linux-gnu/4.4.3/cc1: error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory
After I reported this to the administrator, he added /lusr/opt/mpfr-2.4.2/lib:/lusr/opt/gmp-4.3.2/libto mine LD_LIBRARY_PATH. After that, I get the following error:
mike@canon:~$ gcc test.c
cc1: error: unrecognized command line option "-L/lusr/opt/mpfr-2.4.2/lib"
Firstly, my system administrator was not completely sure that this was the best workaround (although he said that it worked for him ...), is there a better solution?
Secondly, why am I getting a linker error from ccand how to fix it?
Some information that may be helpful:
mike@canon:~$ env | grep mpfr
OLDPWD=/lusr/opt/mpfr-2.4.2/lib
LD_LIBRARY_PATH=/lusr/opt/mpfr-2.4.2/lib:/lusr/opt/gmp-4.3.2/lib:
mike@canon:~$ echo $LDFLAGS
