Guix: build riscv64 master / v30rc1 fails

janb84 commented at 11:22 am on September 18, 2025: contributor

Is there an existing issue for this?

I have searched the existing issues

Current behaviour

While building a guix-build of v30rc1 or main for riscv64-linux-gnu architecture fails with :

0[100%] Linking CXX executable ../../bin/test_bitcoin
1riscv64-linux-gnu-ld: CMakeFiles test_bitcoin.dir/main.cpp.o: in function "boost::fpe::disable(unsigned int)':

5[100%] Built target test_bitcoin make: 
6*** [Makefile: 146: alll] Error 2

building tag version 29.0 / 29.1 / 29.2rc1 works , other architectures also build as expected.

Building on aarch64 nixos 25.05 / M1 max

Expected behaviour

Successful build

Steps to reproduce

0git clone https://github.com/bitcoin/bitcoin.git -b v30.0rc1 --depth 1
1cd bitcoin
2env HOST='riscv64-linux-gnu' ./contrib/guix/guix-build

Relevant log output

Can you provide more info? These warnings have existed for years (i.e are in the 29.x branch that builds for you), and build warnings shouldn’t cause guix build failures.

going to hunt down some more information.

The difference between 29.x and master / v30.0.rc1 on line 146 of the make file is IPC:

line 146:

0if(ENABLE_IPC AND WITH_EXTERNAL_LIBMULTIPROCESS)
1  find_package(Libmultiprocess REQUIRED COMPONENTS Lib)
2  find_package(LibmultiprocessNative REQUIRED COMPONENTS Bin
3    NAMES Libmultiprocess
4  )
5endif()

@janb84

Could you please check your build log for the actual error message, which may appear many lines earlier?

janb84 commented at 12:27 pm on September 18, 2025: contributor

Added console log, and build logs

CMakeError.log CMakeOutput.log console.log

hebasto commented at 12:35 pm on September 18, 2025: member

Added console log, and build logs

console.log

Does it include stderr output as well?

Unfortunately not, just piped the output to a file. Working on it :)

Going to close this issue, it was a memory exhaustion problem.

Seems like V30 needs just a little more memory to build than V29.x

0collect2: fatal error: ld terminated with signal 9 [Killed]
1compilation terminated.

4make[1]: *** [CMakeFiles/Makefile2:1991: src/qt/CMakeFiles/bitcoin-gui.dir/all] Error 2
5make[1]: *** Waiting for unfinished jobs....

Thanks for the help. Allocated just a bit more memory for the VM and it builds.
