Building spring for raspberry pi 2 (armv7-a)

Post by teteros »

I'm interested in building spring for the ARM architecture for spring-dedicated autohosting purposes. This post is intended a follow up to thisthread started by a different user

Using current spring git, as that has the required fixes for compiling without streflop

Code: Select all

gcc --version
gcc (GCC) 7.1.1 20170528
cmake flags used in the buildscript

Code: Select all

cmake . \
	-DMARCH_FLAG=armv7-a \
	-DENABLE_STREFLOP=FALSE \
	-DAI_TYPES=NONE \
	-DCMAKE_INSTALL_PREFIX=/usr \
	-DDATADIR=share/spring \
	-DCMAKE_SKIP_RPATH=YES
make
gcc flags in /etc/makepkg.conf (where arch linux stores compile settings)
These are specific to the cortex-a7 processor in the rpi2, as rpi3 for example is armv8, so you'd need to change these if you were to test compile yourself on a different arm device.

thanks for following up on this.

cpuid doesn't exist as an ARM instruction, but isn't needed when building without streflop so just replace

Code: Select all

#if defined(__GNUC__)
by

Code: Select all

#if 0
in rts/System/Platform/CpuID.cpp#L26 to bypass it. an official fix will be pushed later.

Thanks, used the workaround but noticed you've pushed 851865f which works as well.

Now getting

looks like ucontext_t isn't an alias for unw_context_t on ARM distro's; changing the two

Code: Select all

#if defined(__APPLE__)
lines to

Code: Select all

#if (defined(__arm__) || defined(__APPLE__))
should help.

Thanks with this patch as instructed, spring-dedicated (only) compileswhich was my objective indeed. Updated the PKGBUILD in the OP with the CMAKE flags needed. Specifically,

Code: Select all

-fPIC
CXX/C FLAG was necessary or the linker failed.

Now I can test it out. If there's interest in providing official ARM builds for spring-dedicated I'd like to help.
Seems (hard float) armv6 (rpi v1) armv7 (rpi v2, odroid c1/xu) and armv8 x64 (rpi v3, odroid c2) are most common.

For completion's sake, an engine-headless/legacy build fails with this log:
