Doubts using the precompiled binaries

[marco restelli]

Hi all,
   I am experimenting with the precompiled binaries from the GCC Wiki,
and in particular with gcc-6.3.0.

I have two questions.


1) I get an error trying to link without -fno-use-linker-plugin

gfortran *.o -o test
collect2: fatal error: cannot find 'ld'
compilation terminated.

>From the documentation, I see that this should not be a problem with
ld >= 2.21, and I have 2.26.1. Also, using gfortran compiled by myself
I don't need this option. Is this expected?


2) Trying to do static linking with "-static" I get the error

<local-installation-path>/bin/../lib/gcc/x86_64-pc-linux-gnu/6.3.0/../../../../lib64/libgfortran.a(unix.o):
In function `tempfile':
/tmp/gcc-6.3.0-build/x86_64-pc-linux-gnu/libgfortran/../../../gcc-6.3.0-source/gcc-6.3.0/libgfortran/io/unix.c:1208:
undefined reference to `__secure_getenv'
collect2: error: ld returned 1 exit status

Again, I don't see this problem using gfortran compiled by myself. How
could I fix this?


Thank you,
   Marco
