New issue 662 by [email protected]: zip_output_unittest.sh inevitably
fails when compiling with MinGW
http://code.google.com/p/protobuf/issues/detail?id=662
I've compiled zlib v1.2.8 with MinGW (which produced lib/libz.a,
lib/libz.dll.a, bin/zlib1.dll and the headers in include) and I'm trying to
build/test protobuf with --with-zlib option.
I'm building Protobuf 2.5.0 with patches to atomicops*.h (fix
MemoryBarrier), configure.ac and gtest/configure.ac (add -no-undefined to
LDFLAGS on WIndows) applied.
My flags/configure options look like this:
CFLAGS/CXXFLAGS/CPPFLAGS = -DNDEBUG -Wno-unused-local-typedefs
-Izlib/include -m32
LDFLAGS = -static-libgcc -static-libstdc++ -Lzlib/lib -Lzlib/lib # (I've
also tried putting libz.a here or -Wl,-Bstatic -lz)
./configure --prefix=/some/folder --disable-services --with-zlib
make
make check
All tests pass (including IoTest.Gzip*, IoTest.Zlib* and
IoTest.Compression*), however no matter what I do the very last test (that
checks zcgzip/zcgunzip roundtrip) always fails:
+ TESTFILE=Makefile
+ ./zcgzip
+ gunzip
+ cmp - Makefile
- Makefile differ: char 1731, line52
gunzip: stdout: Broken pipe
FAIL: google/protobuf/io/gzip_stream/unittest.sh
I've tried explicitly linking in libz.a statically which doesn't seem to
help.
