compilation fails for CC="ccache gcc"

my system is Linux, openSUSE 12.2 milestone 3, x86_64.

Michal,

Can you show how this is failing for you? It works fine for me on Mac OS X. https://gist.github.com/2785635

your gist shows that code was compiled with

/usr/local/Cellar/ccache/3.1.6/bin/ccache /Applications/Xcode.app/Contents/Developer/usr/bin/gcc

It looks like CC was ignored in this way, when I repeated your steps I got:
https://gist.github.com/934919c7f8c22ce81fe7

I see. 1.6.7.2 fails for me on the same spot (with a slightly different error message).

Does it work for you on the master? (Since I doubt that there will be another 1.6.x release, we should focus on the master branch.)

It's better as the paths look more sane - but still failing https://gist.github.com/464aeb5404cc8c3163b6

Michal,

To think, we take ccache into account if it is available. See https://github.com/jruby/jruby/blob/ab78ce9179fa13d2610cf9a04632d475651ddd35/cext/src/Makefile#L55

It seems to me that my ccache fails differently from yours when ccache invokes a program that doesn't meet the expectations.

my ccache version is 3.1.7

for me what happens is that
https://github.com/jruby/jruby/blob/ab78ce9179fa13d2610cf9a04632d475651ddd35/cext/src/Makefile#L309

uses CC with ccache inside,

maybe $(CC) could be changed to:

$(patsubst %ccache,,$(CC))

which ensures there is no ccache duplication? - I have tested it on my machine and it worked.

Michal,

Would you like to put a patch together, so we can give you credit for the fix?

done https://github.com/jruby/jruby/pull/180

Right now the behavior changes depending on the platform, Makefile is vulnerable for existing user environment.

I guess solution could be to reset environment on top and overwrite platform differences after.

Merged.
