* To build on OSX (32bit)
export CC=/Developer/usr/bin/llvm-gcc
export CXX=/Developer/usr/bin/llvm-g++
export CFLAGS="-m32 -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 -Os -fvisibility=hidden"
export CXXFLAGS="$CFLAGS"
$ ./configure --enable-shared=no
Note that in xcode4 beta builds /Developer would be replaced with /Xcode4
* To build on linux x86:
export CC=/path/to/gcc
export CXX=/path/to/g++
export CFLAGS=-fvisiblity=hidden
export CXXFLAGS=-fvisiblity=hidden
export LDFLAGS="-static-libgcc"
./configure --enable-shared=no
* To build on linux x86_64:
export CC=/path/to/gcc
export CXX=/path/to/g++
export CFLAGS=-fvisiblity=hidden
export CXXFLAGS=-fvisiblity=hidden
export LDFLAGS=-static-libgcc
./configure --with-pic --enable-shared=no
alternatively, just put all those variables on the configure line (note that LIBS is expressed in terms of the path to g++, not the CXX variable):
./configure CC=/path/to/c-compiler CXX=/path/to/c++-compiler [LDFLAGS=-static-libgcc] [-m32] [--with-pic] --enable-shared=no
This will build src/protoc (the compiler binary) and src/.libs/libprotobuf.a (among others).
publish protoc into src/devtools/bin/<platform>/
publish libprotobuf.a gets into src/lib/<platform>/release
