Hi guys,

sorry for asking such a stupid question here: I wanted to install and use
Fortran on my Mac (never used it before) and ran into the problems with
compiling described here.

I have basically two questions:

1) which one of the patches reported and listed above shall I use?
2) I tried all of them, but I seem to have difficulties implementing them.
Someone suggested to go to the appropriate directory where gcc is stored (i.e.
SSD1 ▸ Applications ▸ Xcode ▸ Contents ▸ Developer ▸ usr ▸ bin) store the patch
file there (as a .diff, right?) and then execute in the terminal

patch -p1 < patchfilename.diff

then, i get

wlan251-121:patch3 Derrick$ patch -p1 < patch.diff
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git a/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc
b/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc
|index 196eb3b..d55e200 100644
|--- a/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc
|+++ b/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc
--------------------------
File to patch: 

i enter gcc, and then i get

patching file gcc
Hunk #1 FAILED at 835.
1 out of 1 hunk FAILED -- saving rejects to file gcc.rej
can't find file to patch at input line 18
Perhaps you used the wrong -p or --strip option?

I am really new to all of this... any hint on how to implement one of the
patches, and ideally which patch to use, would be very much appreciated. thank
you, best,
derrick
