Re: Help gpsim F-9 builds on x86_64 and i386 but fails on ppc

Below is what looks like the relevant part of the build log.
Any suggestions on why this is failing on the ppc but not on x86_64 and i386?

Well, with a patch the build succeeds:
http://koji.fedoraproject.org/koji/taskinfo?taskID=811499
srpm is available from:
http://koji.fedoraproject.org/scratch/mtasaka/task_811499/

Without the patch,
build.logs show the difference between x86_64 and ppc like:
----------------------------------------------------------
-checking for ppc-redhat-linux-gnu-gcc... +checking for x86_64-redhat-linux-gnu-gcc... no checking for gcc... gcc
@@ -130,34 +130,68 @@
checking for unistd.h... yes checking for GNU Readline library, version 2.0 or newer... -no (it is present but too old to use)
+yes, installed version is 5.2

So by some reason libreadline.so is not found or so.
----------------------------------------------------------

I tried to print out what config.log says and it is here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=811491

build.log shows:
----------------------------------------------------------

However, in readline.h rl_completion_append_character is just "extern int"
and this is actually wrong.

Applying a patch against acinclude.m4 is needed. If you don't want to call
autoconf, modify configure directly.
