Building for Linux ARM

Closed this issue 6 years ago · 9 comments

Hi.

I am trying to build a test program with siamese on a raspberry pi using the following g++ command:

g++ -D LINUX_ARM -Wall -o Siamese_test -I../../Common/Siamese/include -L/usr/lib -L/usr/local/lib Siamese_test.cpp ../../Common/Siamese/include/PacketAllocator.cpp ../../Common/Siamese/include/SiameseCommon.cpp ../../Common/Siamese/include/SiameseTools.cpp ../../Common/Siamese/include/SiameseEncoder.cpp ../../Common/Siamese/include/SiameseDecoder.cpp ../../Common/Siamese/include/gf256.cpp ../../Common/Siamese/include/siamese.cpp ../../Common/Siamese/include/Logger.cpp  -lstdc++ --std=c++11 -w -fpermissive

I had to define LINUX_ARM for it to detect the OS and architecture. Still the compiler gives the following error:

../../Common/Siamese/include/SiameseDecoder.h:510:62: error: ‘NextAlignedOffset’ was not declared in this scope
         unsigned unalignedEnd = NextAlignedOffset(columnStart);
                                                              ^
../../Common/Siamese/include/SiameseDecoder.h:510:62: note: suggested alternative:

 PKTALLOC_FORCE_INLINE unsigned NextAlignedOffset(unsigned offset)
                                ^~~~~~~~~~~~~~~~~

The problem seems to be with NextAlignedOffset. I have checked but cannot find why. The function is used in SiameseDecoder.h and this file includes PacketAllocator.h.

The test program builds correctly osx with clang++.

Is there a recommended way to build Siamese on linux ARM?

Thanks.

This is my g++ version:

g++ (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516

Doesn't look like I added a CMakeLists file for this project. It seems to work fine if I add pktalloc:: in front of the symbol that is missing.

Answer 5 · 2019-05-01T22:33:22.000Z

So I should change, in PacketAllocator.h:

PKTALLOC_FORCE_INLINE unsigned NextAlignedOffset(unsigned offset)

for

PKTALLOC_FORCE_INLINE unsigned pktalloc::NextAlignedOffset(unsigned offset)

Or in the invocation in SiameseDecoder.h?

Answer 6 · 2019-05-01T23:33:53.000Z

I changed the one in SiameseDecoder.h to get it working

Excellent. Will try that tomorrow.

Thanks!

Answer 8 · 2019-05-02T05:01:42.000Z

Pushed a CMakeLists and that code change

Answer 9 · 2019-05-02T13:27:36.000Z

Excellent.

Got it built using your changes.

Thanks!!
