I failed to find some architecture specific issues (as long as
ifneq ($(filter nojava,$(DEB_BUILD_PROFILES)),)
is not filtering for certain architectures implicitly.)
I think the issue is connected to parallel builds. After comparing
build logs which look pretty similar between amd64 and armel I suspected
that there is some issue with parallel builds and forced --no-parallel
with the result that the build now even fails for amd64:
dh_auto_build --no-parallel --sourcedirectory src -- default java
cd src && make -j1 "INSTALL=install --strip-program=true" default java
make[2]: Entering directory '/build/libssw-1.1/src'
g++ -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/build/libssw-1.1=. -fstack-protector-strong -Wformat -Werror=format-security -DSIMDE_ENABLE_OPENMP -fopenmp-simd -O3 -DSIMDE_ENABLE_OPENMP -fopenmp-simd -O3 -fPIC -shared -rdynamic -Wl,-soname,libssw.so.0 -o libssw.so.0 ssw.c ssw.h ssw_cpp.h ssw_cpp.cpp -Wl,-z,relro -Wl,-z,now
cc -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/build/libssw-1.1=. -fstack-protector-strong -Wformat -Werror=format-security -DSIMDE_ENABLE_OPENMP -fopenmp-simd -O3 -DSIMDE_ENABLE_OPENMP -fopenmp-simd -O3 -o ssw-align main.c kseq.h -L. -lssw -lm -lz -Wl,-z,relro -Wl,-z,now
/usr/bin/ld: cannot find -lssw
Michael Crusoe confirmed that
The package builds for me on armel as of
https://salsa.debian.org/med-team/libssw/-/commit/a19c146931e078e0e56abc85684f5a3583165e63
so perhaps the issue was introduced later?
I admit I re-applied former patches to create a static lib which was
kicked by the SIMDE patches but it seems I messed up the Makefile.
Any second pair of eyeballs finding what I might have made wrong
in Git[1] between the commit above and HEAD when re-adding the
static lib that was droped at some point in time?
Kind regards
Andreas.
