wxWidgets fails to build with +universal

[macfreek (Freek Dijkstra)]

I replicate the report of haraoka, as this is a separate issue.

libsdl_mixer was upgraded on 10.5.8(ppc). The build result of wxWidgets(2.6.4&2.8.9&2.9.0) failed as follows.

$ sudo port -dv archive wxWidgets +universal
g++-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags
make: *** [.pch/wxprec_monodll/wx/wxprec.h.gch] Error 1

For the record, I was able to reproduce this bug with both wxWidgets 2.8.9 and 2.9.0.

At some point, the Bakefile script work/wxWidgets-2.9.0/build/bk-make-pch is called, which -at the end of the script- tries to write a dependency file:

/usr/bin/g++-4.0 -mmacosx-version-min=10.5 -I./.pch/wxprec_monodll -D__WXOSX_COCOA__ -DWXBUILDING -I./build/src/tiff/libtiff -I../src/tiff/libtiff -I../src/jpeg -I../src/png -I../src/zlib -I../src/regex -I../src/expat/lib -DwxUSE_BASE=1 -DWXMAKINGDLL -I../src/stc/scintilla/include -I../src/stc/scintilla/src -D__WX__ -DSCI_LEXER -DLINK_LEXERS -dynamic -ET_BITS=64 -I./lib/wx/include/osx_cocoa-unicode-release-2.9 -I../include -I/opt/local/include -DWX_PRECOMP -I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE -O2 -arch i386 -arch ppc -fno-common -fvisibility=hidden -fvisibility-inlines-hidden -o ./.pch/wxprec_monodll/wx/wxprec.h.gch -MMD -MF ./.deps/___pch_wxprec_monodll_wx_wxprec_h_gch.d ../include/wx/wxprec.h

Apparently, this is not allowed, as the error clearly indicates:

g++-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags

I do not know how to solve this. Compiling without the +universal variant works fine on both 32-bit and 64-bit architectures.

User vince had a solution​, although it does not work right away. I modified to patch to patch the correct file (configure instead of bk_make_pch), however when I run it, compiling wxWidgets fails:

ld warning: in monodll_osx_cocoa_toolbar.o, file is not of required architecture
ld warning: in monodll_osx_cocoa_tooltip.o, file is not of required architecture
ld warning: in monodll_osx_cocoa_window.o, file is not of required architecture

ld warning: in /opt/local/lib/libSDL.dylib, file is not of required architecture

[...]

ld: symbol(s) not found
collect2: ld returned 1 exit status

Apparently, this work around is not the correct way to patch this.

Non-solution; removes architecture flags

Replying to software@…:

ld warning: in /opt/local/lib/libSDL.dylib, file is not of required architecture

Presumably, you need to install libsdl with the correct architectures first.

And please remember WikiFormatting when writing in Trac.

The current portfile has the universal variant disabled, so feel free to close this if you don't intend to add a working one.

wxWidgets 2.8.x and earlier won't ever build universal due to Carbon dependency, 2.9.4 (current wxWidgets-devel) builds fine, at least on 10.7
