libbiosig: build fails with universal variant

[ryandesign (Ryan Carsten Schmidt)]

  ld: warning: ignoring file
  CMakeFiles/cmTryCompileExec713066221.dir/testCCompiler.c.o, file was built
  for unsupported file format ( 0xCF 0xFA 0xED 0xFE 0x07 0x00 0x00 0x01 0x03

  linked (i386): CMakeFiles/cmTryCompileExec713066221.dir/testCCompiler.c.o

  Undefined symbols for architecture i386:

  ld: symbol(s) not found for architecture i386

That's odd. CMake compiles without arch flags although CMAKE_OSX_ARCHITECTURES is set to "x86_64;i386":

/usr/bin/clang -DMACPORTS -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
-mmacosx-version-min=10.9 -o 
CMakeFiles/cmTryCompileExec3523348986.dir/testCCompiler.c.o -c

But then it links with arch flags:

/usr/bin/clang -DMACPORTS -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
-mmacosx-version-min=10.9 -Wl,-search_paths_first
-Wl,-headerpad_max_install_names -L/opt/local/lib
-Wl,-headerpad_max_install_names -lz -lcholmod
-Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
-arch x86_64 -arch i386
CMakeFiles/cmTryCompileExec3523348986.dir/testCCompiler.c.o -o
cmTryCompileExec3523348986

Any ideas?

More general patch that uses the private getline implementation only on SL and independently of MacPorts. See ticket #42152.

libbiosig Portfile diff to use only system zlib

[neurodroid (Christoph Schmidt-Hieber)]

Apologies, the attached files belong to ticket #42159.

[ryandesign (Ryan Carsten Schmidt)]

The problem is the portfile overrides the cflags and cxxflags the portgroup sets. Fixed in r117319.
