[GCC front end] trying to install sample_fe but fail in make

[charfi asma]

Hi, 

I looked at the config.log in libgcc and As Andi predict, it is a problem of 
libmpc (please find bellow a snipset of config.log input )

but mpc is well installed and when I enable the sample_fe front end, the 
configure, make and make install work perfectly with gcc 4.4.4
the problem comes from dev_gcc that I download from git, although I am using the 
last version of mpc: 0.82.
should I use other version ??
I verified that the file libmpc.so.2 exists in the /usr/local/lib but tthe 
config.log said "cannot open shared object file: No such file or directory"

any idea ??

Yes, this might occur if you use older versions (for example built for 4.4) in 
4.5. builds. The handling of GTY(()) slightly changed with 4.5 . But, you 
already corrected it accordingly.

You'll need to look at the file config.log in directory 
/export/home/charfi/objdir/i686-pc-linux-gnu/libgcc. It will tell you what's 
missing. Maybe you're just missing a depending library (mpc, mpfr, gmp).

Cheers,
