Description APN-Pucky 2023-11-05 18:07:16 UTC

I get following error from go-md2man on an armv7l (Raspberry Pi 2B V1.1):

/usr/lib/go/pkg/tool/linux_arm/link -o $WORK/b001/exe/a.out -importcfg $WORK/b001/importcfg.link -installsuffix shared -X=runtime.godebugDefault=panicnil=1 -buildmode=pie -buildid=mV9aGXB-e88B0ONORfCM/Ofo08pTQxLjBxnfKtXbV/_2PgZag1BPR-iOF0_C2J/mV9aGXB-e88B0ONORfCM -extld=x86_64-pc-linux-gnu-gcc $WORK/b001/_pkg_.a
# github.com/cpuguy83/go-md2man/v2
loadinternal: cannot find runtime/cgo
/usr/lib/go/pkg/tool/linux_arm/link: running x86_64-pc-linux-gnu-gcc failed: exec: "x86_64-pc-linux-gnu-gcc": executable file not found in $PATH

make: *** [Makefile:19: bin/go-md2man] Error 1

However, compiling the git version works well. From there I found the difference is in the GOFLAGS (https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/go-module.eclass#n369). By adding them I get the same error from a non-system compile:

~/git/go-md2man # rm -rf  ~/.cache/go-build/ && rm -rf bin &&  make GOFLAGS="-buildmode=pie" BUILD_FLAGS="-mod=vendor" build
# github.com/cpuguy83/go-md2man/v2
loadinternal: cannot find runtime/cgo
/usr/lib/go/pkg/tool/linux_arm/link: running x86_64-pc-linux-gnu-gcc failed: exec: "x86_64-pc-linux-gnu-gcc": executable file not found in $PATH

make: *** [Makefile:19: bin/go-md2man] Error 1

Thus, I expect the solution is to remove -buildmode=pie for arm?
