Hi Brad
Sorry it took me a while to reply -- i actually installed Studio 12
Express on my Linux laptop to make sure the flags are the same as on
Solaris. :-)
Studio won't like -fPIC (and pretty much none of the GCC flags,
actually).
Could you please try these:
export CPPFLAGS=-I/opt/sun/sunstudio12/prod/include/CC \
-I/opt/sun/sunstudio12/prod/include/CC/Cstd \
[ + add more includes here ]
For 32-bit:
export CFLAGS=" -Xc -erroff=%all -errshort=full -errfmt=error \
-errwarn=%none -xO3 -s -xjobs=2 -xregs=no%frameptr \
-xprefetch=auto -xprefetch_auto_type=indirect_array_access \
-xprefetch_level=3 -xbuiltin=%all -xcsi -xinline=%all \
-xustr=ascii_utf16_ushort -z combreloc -z redlocsym \
-z nodefaultlib -z now -z rescan \
-z absexec -xildoff -xldscope=symbolic \
-xrestrict=%all -xF=%none -xalias_level=std \
-xthreadvar -lc -lpthread -lposix4 -lrt \
-mt -D_REENTRANT -D__EXTENSIONS__=1 \
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 \
-D_XPG4 -D_XPG4_2 -D_XPG5 -D_XPG6 \
-D_POSIX_PTHREAD_SEMANTICS -D_XOPEN_SOURCE=600 \
-D_POSIX_C_SOURCE=200112L -D_STDC_C99 \
-xtarget=pentium4 -xarch=sse2 \
-xchip=pentium4 -xcache=8/64/4:256/128/8"
[ some of the defines might have to be slightly adjusted for Linux,
these are for Solaris]
export CXXFLAGS=" -features=%all,extensions,tmplife,tmplrefstatic \
-instances=global -template=geninlinefuncs -verbose=template \
-xO3 -s -xlang=c99 -xregs=no%frameptr -xprefetch=auto \
-xprefetch_auto_type=indirect_array_access -xprefetch_level=3 \
-xbuiltin=%all -xinline=%all -xjobs=2 \
-xustr=ascii_utf16_ushort -z combreloc -z redlocsym \
-z nodefaultlib -z now -z rescan -z absexec \
-xldscope=symbolic -xalias_level=compatible \
-Qoption ccfe -complextmplexp -Qoption ccfe -features=gcc \
-lc -lpthread -lposix4 -lrt -mt -D_REENTRANT \
-DNDEBUG -KPIC -xrestrict=%all -xF=%none -xthreadvar \
-D__EXTENSIONS__=1 -D_LARGEFILE_SOURCE \
-D_FILE_OFFSET_BITS=64 -D_XPG4 -D_XPG4_2 \
-D_XPG5 -D_XPG6 -xtarget=pentium4 -xarch=sse2 \
-xchip=pentium4 -xcache=8/64/4:256/128/8 "
This is a very optimized build. Some of the options are crazy. For a
vanilla debug build, you could try
export CXXFLAGS=" -features=%all,extensions,tmplife,tmplrefstatic \
-instances=global -template=geninlinefuncs -verbose=template \
-g -xlang=c99 -xustr=ascii_utf16_ushort -z combreloc -z redlocsym \
-z nodefaultlib -z now -z rescan -z absexec \
-xldscope=symbolic \
-Qoption ccfe -complextmplexp -Qoption ccfe -features=gcc \
-xildoff -lc -lpthread -lposix4 -lrt -mt -D_REENTRANT \
-KPIC -D__EXTENSIONS__=1 -D_LARGEFILE_SOURCE \
-D_FILE_OFFSET_BITS=64 -D_XPG4 -D_XPG4_2 \
-D_XPG5 -D_XPG6 "
export LDFLAGS=" -L/opt/sun/sunstudio12/prod/lib -lCrun -lCstd "
[ + add more needed libraries here ]
For 64-bit you can change the following:
-xtarget=opteron -xarch=amd64 -xchip=opteron \
-xcache=8/64/4:256/128/8
and change LDFLAGS to
export LDFLAGS=" -L/opt/sun/sunstudio12/prod/lib/amd64 \
-lCrun -lCstd "
[ + add more 64-bit libraries ]
This will build for Opterons. For a generic 64-bit, you can try
-xtarget=generic64 -xarch=amd64
for $(CXXFLAGS) and $(LDFLAGS)
When creating *.a (archive) libraries, you should do:
$(CXX) $(CXXFLAGS) -xar -o <libarchive-name.a>.
When linking/creating a shared lib:
$(CXX) $(CXXFLAGS) $(LDFLAGS) -G -h'$(SONAME)' \
<list-of-object-files> -o <shared-library-name.so>
A quick way of finding out Studio's cc, c99 and CC flags is:
/opt/sun/sunstudio12/bin/cc -xhelp=flags
/opt/sun/sunstudio12/bin/c99 -xhelp=flags
/opt/sun/sunstudio12/bin/CC -xhelp=flags
The -xtarget=, -xarch= and -xchip= are important. You can get very
nice performance by setting them for the right architecture (with the
caveat that if you compile something for P4/SSE2 or Opteron, it will
not work on earlier pentiums).
If you run into problems with macros, you can pass
-xdumpmacros=%all to CC, and it will print out the macro expansions.
You can also use cc, c99 and CC as CPP:
export CPP="${CC} ${CFLAGS} ${CPPFLAGS} -E "
export CXXCPP="${CXX} ${CPPFLAGS} ${CXXFLAGS} -E "
I've built QCA + QT 3.x and 4.x with Studio 10 and 11 (on Solaris) and
they build and work very very nicely.
Please let us know how it goes. :-)
