Bug #3178
closedscons: build_fullstatic with_lua=1 fails due to redefinition error
Description
There is a full-static-build error for lighttpd using a Docker Alpine container on Debian 11. The failure is a link error due to redefinition related to algo_hmac.c which can be solved by deleting line 119 of src/SConscript. This line relates to mod_secdownload which appears to be deprecated. The issue is that the algo_hmac.c object is linked for mod_secdownload and for mod_magnet which can cause redefinition errors in static builds.
The sequence:¶
% sudo docker run -it alpine
# apk update && apk upgrade
# apk add curl scons gcc make perl lua-dev musl-dev openssl-dev \
bsd-compat-headers zlib-dev pcre2-dev openssl-libs-static \
zlib-static
# curl -L 'https://download.lighttpd.net/lighttpd/releases-1.4.x/lighttpd-1.4.67.tar.gz' -o lighttpd-1.4.67.tar.gz
# tar xvf lighttpd-1.4.67.tar.gz
# cd lighttpd-1.4.67
# scons build_fullstatic=1 \
build_dynamic=0 \
with_openssl=1 \
with_zlib=1 \
with_pcre2=1 \
with_lua=1 \
prefix=/path/to/installdir \
install
The scons warning:¶
scons: warning: Two different environments were specified for target algo_hmac.os, but they appear to have the same action: $SHCC -o $TARGET -c $SHCFLAGS $SHCCFLAGS $_CCCOMCOM $SOURCES File "/lighttpd-1.4.67/src/SConscript", line 315, in <module>
The linker error:¶

Thanks for all your work.

Thanks for the report.
mod_secdownload is scheduled to be removed in the next lighttpd release, currently estimated early January to match the previous year of deprecation warnings.

- Status changed from New to Patch Pending
- Target version changed from 1.4.xx to 1.4.68
For a workaround until lighttpd 1.4.68 in Jan, you can use the following patch to remove mod_secdownload, or you can build without lua, or you can keep both and manually remove 'algo_hmac.c' from the mod_secdownload line to avoid the duplication.
