Not Able to compile protobuf for mips platform #670

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. executed ./configure  --prefix=/home/inigo/  --with-protoc=../bin/protoc  
--host=mips-linux --build=mips-linux-uclibc 
CC=/home/inigo/bin/mips-linux-uclibc-gcc 
CXX=/home/inigo/bin/mips-linux-uclibc-g++
2.make
3.

What is the expected output? 

it should compile without any issues.

What do you see instead?

What's the version you are using? I believe we just added mips support in the 
latest 2.6.0 release.

Thanks for the reply. I was using 2.5.0 and as per your reply, now I downloaded 
the 2.6.0 protobuf and I am seeing the same above issue issue.1. 

If manually define the __MIPSEL__ then the compilation is failing with the 
following errors. Please help me to resolve this problem.

Can you check whether your compilation has hit this header file?

After I manually define the __MIPSEL__ in the compilation then the above .h 
file is getting included in the compilation and I am getting the following 
error. Please let me know if there is any issue with my compilation. If I dont 
define then the above .h file didnt get included in the compilation.
Steps
./configure  --prefix=/home/inigo/gbp/  --with-protoc=../bin/protoc  
--host=mips-linux CC=/home/inigo/bin/mips-linux-uclibc-gcc 
CXX=/home/inigo/bin/mips-linux-uclibc-g++ CXXFLAGS=-D__MIPSEL__

make

and getting the following compilation error.
./configure  --prefix=/home/inigo/gbp/  --with-protoc=../bin/protoc  
--host=mips-linux CC=/home/inigo/bin/mips-linux-uclibc-gcc 
CXX=/home/inigo/bin/mips-linux-uclibc-g++ CXXFLAGS=-D__MIPSEL__

What platform would you like to use it on?
Can you take a recent MIPS cross-toolchain and build it with it?
If your platform is MIPS32 or MIPS32R2, passing -mips32 or -mips32r2 will help 
too, in case your compiler defaults to mips1.

Note that protobuf 2.4.1 seems to cross-compile fine to MIPS

2.5.0 and 2.6.1 both fail for me as well with the reported error

I used gcc 4.4 toolchain on debian, similar to instructions here:
https://moozing.wordpress.com/2011/04/05/cross-compile-in-debian/

And:
configure -host=mips --disable-shared CC=mips-linux-gnu-gcc 
CXX=mips-linux-gnu-g++

After more digging it appears to build to MIPS32 (2.4.1, 2.5.0, 2.6.1):

./configure -host=mips32 CXX=mips-linux-gnu-g++ CXXFLAGS="-D__MIPSEL__ 
-march=mips32" --disable-shared

After make:

file src/protoc
src/protoc: ELF 32-bit MSB executable, MIPS, MIPS32 version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.6.18, 
BuildID[sha1]=0x25cf7add05893f48e8c5bd2b256bd784d81045e4, with unknown 
capability 0x41000000 = 0xf676e75, with unknown capability 0x10000 = 0x70401,
