795327 - mach is confused if 'configure' run is interrupted on Linux

Status: RESOLVED WORKSFORME

(Firefox Build System :: General, defect)

Description

[Jim Blandy :jimb]

To reproduce, on Linux:

- Delete your build tree.

- Type: ./mach build

- While the configure script is running, hit C-c. I think this needs to happen early in the process. I hit it at this point, and was able to reproduce the problem:

0.77 checking how to run the C preprocessor... gcc -E

Perhaps modifying the configure script with an "exit 2" at that point, conditional on an environment variable, could make it reproducible.

- Type, again: ./mach build

The second 'mach build' dies as follows:

0.45 checking for c++... c++
0.52 checking whether the C++ compiler (c++  ) works... cat: conftest.C: No such file or directory
0.52 no
0.52 configure: error: installation or configuration problem: C++ compiler cannot create executables.
0.52 *** Fix above errors and then restart with               "/usr/bin/gmake -f client.mk build"
0.52 gmake[2]: *** [configure] Error 1
0.52 gmake[1]: *** [/home/jimb/moz/mc/obj-rel/Makefile] Error 2
0.52 gmake: *** [build] Error 2

I think this is a core build system bug and not something specific to mach. Is bug 795326 related?

Comment 2

jimb: We've pushed a number of changes to mach regarding process handling and handling of SIGINT/C-c. I'm optimistic that if you pull m-c you'll find this problem has magically gone away.

Please reopen if you experience otherwise.
