Description Ihar `Philips` Filipau 2007-04-21 12:04:48 UTC

gdb's configure calls short compiler name what breaks its distributed build.

Not once I have spotted during emerge' ./configure run output of x86 gcc complaining about unrecognized - powerpc specific - options.

Reproducible: Always

Steps to Reproduce:
1. main host on powerpc
2. compile farm on x86 with crossdev -t powerpc
3. configure distcc/distccd
4. on powerpc do "emerge gdb"

Actual Results:  
1. In configure output watch for x86 gcc complaining about unsupported options.
2. configure fails without error message (I presume something compiled during configure run - and compiled remotely with foreign gcc - fails to run on host due to different arch.)

Expected Results:  
No compiler errors should be reported and configure should succeed w/o problems as in non-distributed build. Build should go on.

Comment 1 Ihar `Philips` Filipau 2007-04-21 12:08:14 UTC

Watching now non-distributed build process, it seems that GDB does ignore configure's "--host" parameter entirely: it always calls "gcc" instead of fully qualified compiler name.

What version was this with?  When compiling the newest ~arch gdb it seems to use the full compiler name:

x86_64-pc-linux-gnu-gcc -c -DHAVE_CONFIG_H    -I. -I.././readline -DRL_LIBRARY_VERSION='"5.1"' -march=nocona -O2 -pipe terminal.c
