Bug 209307 – app-emulation/bochs-2.3.6 fails configure on amd64 or when USE=sse

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexandre Rostovtsev (RETIRED) 2008-02-08 00:56:42 UTC]

The configure script for bochs-2.3.6 requires --enable-sse=2 when the --enable-x86-64 option is used, or it dies with an error:

[...]
checking for FPU emulation... yes
checking for VME support... yes
checking for MMX support... yes
checking for 3DNow! support... no
checking for SSE support... SSE1
configure: error: x86-64 needs SSE2 support

!!! Please attach the following file when seeking support:
!!! /var/tmp/portage/app-emulation/bochs-2.3.6/work/bochs-2.3.6/config.log
 * 
 * ERROR: app-emulation/bochs-2.3.6 failed.

In other words, on amd64, the ebuild must completely ignore the sse USE flag (put it in package.use.mask), and *always* pass in "--enable-sse=2"

fixed bochs-2.3.6.ebuild

Ebuild that makes configure not die on amd64.

Actually: there is also a similar problem on non-amd64 architectures if USE=sse (in that case, the configure script requires the cpu-level to be set to 6, or it dies).

ebuild to fix both issues

Better ebuild, now fixes configure issues both on amd64 and on x86 with USE=sse.

the ebuild changes from 2.3.6 are significative when compared to 2.3.5 and so the use of --enable-x86-64 with all the different added CPU emulation flags will need to be adjusted further as shown by trial/error in this bug.  the safest option will be to just remove x86_64 support all together hoping that the right combinations of flags can be abstracted correctly for all possible combinations.

USE="debugger" might need also additional testing.

[Comment 6 Fred Krogh 2008-02-13 23:01:10 UTC]

Even though I have sse in make.conf and/or precede an emerge of bochs with env USE="sse", it shows (-sse) as the use flag.  Thus there appears no way to emerge this for me on an opteron system.

[Comment 7 Sven 2008-02-21 13:19:23 UTC]

if there is a "--enable-sse=2" then where is the sse2 useflag?
that would also fix it for amd64: i could set the sse2 useflag, and bochs would compile.
