Hello,
This may not be a protobuf issue per se, but I'm hoping someone else knows
how to solve this problem.
It's cost me over a day now.
The situation is that I am trying to cross-compiler protobuf 3 for an ARM
target.
The host system is Windows, but I am running in a CYGWIN environment, using
the Linaro arm cross tools.
My configure command is:
./configure --build=i686-pc-cygwin --host=arm-linux-gnueabihf
--target=arm-linux-gnueabihf CXXFLAGS=-std=gnu++11
CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++
--with-protoc=/usr/bin/protoc --prefix=/home/Admin/protobuf_build
The failure is that at some point int the build process,
(for libprotoc.la), arm-linux-gnueabihf-g++ is going to try to pull in
src/.libs/libprotobuf.so, which is a link to libprotobuf.so.17.0.0.
If, under Cygwin, I specify native links, then the error is:
/.libs/libprotobuf.so: file format not recognized; treating as linker
script
If I use Cygwin=winlinks ( so the link is a shortcut ), then the file is
not found.
Playing with the command line, it looks like the Linaro compiler cant deal
with symbolic links of any kind under Cygwin, unless it is process through
the cygpath command.
Is there any way this can be configured ? or is there another known
solution to this ? I've tried to contact Linaro, but there hasn't been a
response.
Thanks,
Joe
