GEOS 3.0 won't link on ARM-EABI platform

[jcrepetto]

I am trying to compile geos-3.0.3 for the ARM architecture. I am using GCC 4.2.1 and GLIBC 2.5, the toolchain can be freely downloaded at ​http://www.codesourcery.com/gnu_toolchains/arm/portal/release313.

I have used the following commands :

./configure --host=arm-none-linux-gnueabi --prefix=/home/jcr/arm-2007q3
make

All the files are compiled, but there is a problem with linking :

Sorry, we need a patch on this that you like, we don't have ARM systems lying around to re-create it.

Milestone 3.0.1 deleted

[jcrepetto]

You don't need an ARM system to recreate it. The toolchain mentioned above is a cross-compiler. You just have to install it on your PC, then use it to compile GEOS.

I *suppose* it's directly related to a-little-non-standard ARM EABI optimization. Here is the problem described in details, with GCC 4.2.x:

​C++ PATCH: Key methods for ARM EABI

See ​comment 20 from Andrew Pinski for the ​GCC Bug 25908

I'd suggest to check if this is the same problem you're dealing with. I guess it is, and I'm afraid GEOS has nothing to do with it.

BTW, it's not been planned to be fixed for milestone 3.1.0

I have the same problem (on Synology platform). I do not the problem is the same as the one you reference. It is rather a double definition in the .o files . I did not pinpoint the exact problem but commenting the line in inlines.cpp: #include <geos/noding/snapround/MCIndexSnapRounder.inl>

fixes the issue.

I have this issue in 3.1.1

Replying to pramsey:

I already made a description of the fix in my post, but here is one that I had to redo on 'geos-3.2.0' to make it build:

Above patch helped me compile GEOS-3.2.0 on armv5tel-softfloat-linux-gnueabi with:

• GCC 4.4.1, -Os -march=armv5te -pipe -combine -fomit-frame-pointer -ftree-builtin-call-dce
• binutils 2.19.1-r1
• glibc 2.11-r1
• Gentoo

Thank you!

wmark, jcrepetto: could you try building r3368 from trunk ?

[strk]

r3372 should have fixed this. Feel free to reopen if not.
