I have been following the steps in Peter's answer to How to build Google's protobuf in Windows using MinGW? but make does not complete and errors out.
I am on Win64 and have MinGW with installed the mingw-developer-toolkit, mingw32-base, mingw-gcc-g++, msys-base and additionally mingw32-phtreads-w32.
Under MinGW/msys/1.0 I create the folder /home/<username> and paste the protobuf-3.1.0 source downloaded from github.
I open an MSYS shell, cd into the protobuf dir and run ./autoconfig: the log is here.
Now, the first thing I don't like from the log is:
configure:16556: checking for the pthreads library -lpthreads configure:16589: gcc -o conftest.exe conftest.c -lpthreads -lz >&5 c:/mingw/bin/../lib/gcc/mingw32/5.3.0/../../../../mingw32/bin/ld.exe: cannot find -lpthreads Why is it not finding pthreads when I have it installed?
Then, I proceed with make and get protoc.exe has stopped working with the following crash info:
Problem signature: Problem Event Name: APPCRASH Application Name: protoc.exe Application Version: 0.0.0.0 Application Timestamp: 580a23df Fault Module Name: libprotobuf-11.dll Fault Module Version: 0.0.0.0 Fault Module Timestamp: 580a225f Exception Code: c0000005 Exception Offset: 001171cd OS Version: 6.1.7601.2.1.0.256.4 Locale ID: 2057 Additional Information 1: 4c0d Additional Information 2: 4c0d4d78887f76d971d5d00f1f20a433 Additional Information 3: 4c0d Additional Information 4: 4c0d4d78887f76d971d5d00f1f20a433 and the shell ends with
make[2]: *** [unittest_proto_middleman] Error 5 make[2]: Leaving directory `/home/ok1011/protobuf-3.1.0/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/ok1011/protobuf-3.1.0' make: *** [all] Error 2 Here you can find the make log and error. I am not the only one having this issue.
Any ideas what might be the problem and how to fix it?
