I encountered a slight difficulty linking fortran code with g77 from
gcc-3.1. It fails with cannot find -lfrtbegin. After a brief search I
found this in /usr/local/lib/gcc-lib/i686-pc-linux-gnu as a static
library. Manually adding this path with -L works fine (this directory
also contains libg2c as well).
I tried g77 -print-search-dirs and got:
install: /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/
programs:
=/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/:/usr/lib/gcc/i686-pc-linux-gnu/3.1/:/usr/lib/gcc/i686-pc-linux-gnu/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/bin/i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/bin/
libraries:
=/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/:/usr/lib/gcc/i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/lib/i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/lib/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../i686-pc-linux-gnu/3.1/:/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../:/lib/i686-pc-linux-gnu/3.1/:/lib/:/usr/lib/i686-pc-linux-gnu/3.1/:/usr/lib/
which doesn't appear to be looking for libraries in
/usr/local/lib/gcc-lib/i686-pc-linux-gnu
Back-checking against 3.0.4 showed that the search paths were similar,
however in 3.0.4 libfrtbegin doesn't appear to exist and libg2c is a
static library in the /usr/local/lib/i686-pc-linux-gnu/3.0.4 directory
and not /usr/local/lib/i686-pc-linux-gnu
I haven't tried any other platforms yet with 3.1, so I don't know if
this is only specific to ix86.
Is this an install problem or have I missed something blatently obvious?
