Patch added by commit eee96b0f0a on gcc
9.3.0 must also be applied on gcc 10 and 11 to avoid the following build
failure on numerous packages (babeltrace2, pcsc-lite, tpm2-pkcs11,
etc.):
configure:13774: checking whether pthreads work with -pthread
configure:13868: /home/giuliobenetti/autobuild/run/instance-0/output-1/host/bin/or1k-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -g2 -std=gnu99 -pthread -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 conftest.c >&5
conftest.c:27:26: error: #error "_REENTRANT must be defined"
27 | # error "_REENTRANT must be defined"
| ^~~~~
It should be noted that external bootlins will have to be rebuilt.

Subject: [PATCH] gcc: define _REENTRANT for OpenRISC when -pthread is passed
|
|
|
|
The detection of pthread support fails on OpenRISC unless _REENTRANT
|
|
is defined. Added the CPP_SPEC definition to correct this.
