I installed last 64bits trisquel distro recently, I build gcc 5.2.0 from
source on it. I used exactly the same installation technique than the one I
used (and that worked) on ubuntu 15.04 64bits, which is the following, and
uses isl and cloog optimizations for gcc :
wget https://ftp.gnu.org/gnu/gmp/gmp-6.0.0a.tar.xz
tar -Jxf gmp-6.0.0a.tar.xz
cd gmp-6.0.0/

make -j 4
sudo make install
After that, I wanted to test some c++11 features, so I create a
tst_lambda.cpp file containing this :
#include
#include
using namespace std;
int main()
{
cout /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f1ec2c26000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f1ec2920000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1ec255b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f1ec352d000)
So I went to see in /usr/local/lvm/isl-0.14/lib and found the following
elements :
total 4912
-rw-r--r-- 1 root root 3263234 août 11 14:38 libisl.a
-rwxr-xr-x 1 root root 1000 août 11 14:38 libisl.la
lrwxrwxrwx 1 root root 16 août 11 14:38 libisl.so ->
libisl.so.13.1.0
lrwxrwxrwx 1 root root 16 août 11 14:38 libisl.so.13 ->
libisl.so.13.1.0
-rwxr-xr-x 1 root root 1750046 août 11 14:38 libisl.so.13.1.0
-rw-r--r-- 1 root root 3939 août 11 14:38 libisl.so.13.1.0-gdb.py
drwxr-xr-x 2 root root 4096 août 11 14:38 pkgconfig
and I don't understand : libisl.so.13 points to libisl.so.13.1.0 which is the
same directory as the symlink it is pointed by...
Under Ubuntu 15.04 64bits or under Mac OS X 10.10.5, I don't have such a
linking problem, the linking is done, libisl.so.13.1.0 is found. Under
Trisquel, apparently not... What is the problem ?
