# The distro libcurl.a cannot be linked statically on Alpine: it pulls in
|
||
|
|
# libpsl, libbrotli, libzstd and libnghttp2, whose static archives hold LTO
|
||
|
|
# bytecode from GCC 14 that the installed GCC 15 cannot read ("bytecode
|
||
|
|
# stream ... generated with LTO version 14.0 instead of the expected 15.1"),
|
||
|
|
# so psl_*/Brotli*/ZSTD* never resolve. -fno-lto does not help; the objects
|
||
|
|
# are bytecode, not C.
|
||
|
|
#
|
||
|
|
# static-deps/libcurl.a is curl built without those four libraries, leaving
|
||
|
|
# only LTO-free static deps. Regenerate with: make static-deps
|
||
|
|
#
|
||
|
|
# c-ares is built from source by the same script, for two reasons: a minimal
|
||
|
|
# system often has no libcares.a at all (Void's c-ares-devel ships the shared
|
||
|
|
# library only), and where an archive does exist it can carry the same LTO
|
||
|
|
# bytecode as the distro libcurl.a. Building it also pins the version.
|
||
|
|
#
|
||
|
|
# Archive order matters: libcurl.a pulls in ares_* symbols, so libcares.a has to
|
||
|
|
# come after it on the link line.
