I did this

On CentOS 7/x86_64...

./configure --prefix=$(dirname ${PWD})/wolfssl --enable-static --enable-static=yes --disable-shared --enable-shared=no --enable-all --enable-singlethreaded --enable-distro --disable-fips --enable-tlsv10 --enable-jobserver=no --disable-examples LDFLAGS=-static LIBS=-pthread
make -j$(($(nproc)*2+1))
make install
install -m 644 wolfssl/options.h ../wolfssl/include/wolfssl/
  • configure and attempt to build curl with static wolfssl using...
./configure --prefix=${PWD}-built --disable-shared --enable-shared=no --enable-static --enable-static=yes --with-wolfssl=${PWD}/wolfssl LIBS='-pthread -lm'

This works fine on 7.70.0 - just tested successfully to verify. On 7.71.0, configure errors out with:

checking run-time libs availability... failed
configure: error: one or more libs available at link-time are not available run-time. Libs used at link-time: -lwolfssl -lm -lz -pthread -lm

config.log shows the following:

configure:30213: checking run-time libs availability
configure:30234: gcc -o conftest -Werror-implicit-function-declaration -O2 -Wno-system-headers -I/usr/local/tmp/curl-7.71.0/wolfssl/include  /wolfssl    -I/usr/local/tmp/curl-7.71.0/wolfssl/include  
    -L/usr/local/tmp/curl-7.71.0/wolfssl/lib   conftest.c -lwolfssl -lm -lz -pthread -lm >&5
gcc: error: /wolfssl: No such file or directory
configure:30234: $? = 1
configure: program exited with status 1

I'm wondering where the bare /wolfssl is coming from and if the new -L handling in the autotools setup is causing this. The same pattern seems to work fine with OpenSSL/LibreSSL, mbedTLS, and bearssl, though, so I'm not sure what the difference is with WolfSSL, or if the -L change is completely unrelated.

I expected the following

A src/curl built with static wolfssl.

curl/libcurl version

7.71.0

operating system

CentOS 7 (x86_64)

I tested under CentOS 6 (x86_64) as well with the same results.

This appears to be related to the changes in handling WolfSSL with NTLM and interplay with the WolfSSL --enable-distro and/or --enable-all options. If both (or either) of those config options are removed and WolfSSL rebuilt, I'm then able to build curl 7.71.0 against a static libwolfssl.a as expected. The WolfSSL configure options also don't appear to be cumulative, i.e., --disable-alpn won't actually do that if it's set via --enable-all or --enable-distro.

Will have to tune my WolfSSL config a bit as I think the issue is there, not curl, but this was unexpected as I've been using something like this for months and multiple curl versions. Thanks!

config.log is the first thing to investigate to get some details for this. That bare /wolfssl certainly looks wrong.

(we build with wolfSSL outside of system directories in our CI builds, so very frequently...)

You can perhaps start by showing us the wolfSSL section from curl's configure output when it ran.

Not the OP, but I see the same issue trying to build cURL 7.71.1 with wolfSSL in a Yocto environment.

Quick testing shows that this breaks going from 7.70.0->7.71.0, which would relate it to this commit. It seems like the configure script is trying to take the pkg-config values even if I provide a path to the option.

Configure invoked with:

$ ../curl-7.71.1/configure --build=x86_64-linux --host=aarch64-WaveserverOS-linux --target=aarch64-WaveserverOS-linux --prefix=/usr --exec_prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --libexecdir=/usr/libexec --datadir=/usr/share --sysconfdir=/etc --sharedstatedir=/com --localstatedir=/var --libdir=/usr/lib --includedir=/usr/include --oldincludedir=/usr/include --infodir=/usr/share/info --mandir=/usr/share/man --disable-silent-rules --disable-dependency-tracking --with-libtool-sysroot=/localdisk/workspace/ws_cov/waveserver-build/build/tmp/work/aarch64-WaveserverOS-linux/curl/7.71.1-r0/recipe-sysroot --disable-libcurl-option --disable-ntlm-wb --enable-crypto-auth --with-ca-bundle=/etc/ssl/certs/ca-certificates.crt --without-libmetalink --without-libpsl --enable-debug --enable-optimize --disable-curldebug --disable-ares --without-brotli --disable-manual --disable-dict --without-gnutls --disable-gopher --disable-imap --enable-ipv6 --without-gssapi --disable-ldap --disable-ldaps --without-libidn2 --with-libssh2 --without-mbedtls --disable-mqtt --without-nghttp2 --without-nss --disable-pop3 --enable-proxy --without-librtmp --disable-rtsp --disable-smb --disable-smtp --without-ssl --disable-telnet --enable-tftp --enable-threaded-resolver --enable-verbose --with-wolfssl=/localdisk/workspace/ws_cov/waveserver-build/build/tmp/work/aarch64-WaveserverOS-linux/curl/7.71.1-r0/recipe-sysroot/usr --with-random=/dev/urandom --with-zlib=/localdisk/workspace/ws_cov/waveserver-build/build/tmp/work/aarch64-WaveserverOS-linux/curl/7.71.1-r0/recipe-sysroot/usr/lib/../

Ah, but that 's a slightly different use case though @a5ehren. When building cross-compiled, it shouldn't use the pkg-config file as it's usually not right for that. I'll submit a PR in a sec to address that.

I've confirmed that the commit fixes the config step for my exact case (--with-wolfssl=), but the link for libcurl.so fails with "undefined reference to wolfSSL_DES_ecb_encrypt". This function is hidden behind an extra #ifdef when compared to wolfSSL_DES_set_odd_parity that is tested for in the configure script when checking to add NTLM support (at least in the two versions of wolfSSL I have access to - 4.3 and 4.4). This function (for whatever reason) only gets added to the OpenSSL compatibility layer if the user is building for stunnel, wpa_supplicant, or openVPN support - otherwise it is not present.

Using the plain "--with-wolfssl" fails a Yocto QA check, because the addcflag, etc, doesn't get blanked back to defaults properly.

I've got a pretty good idea of what to do to fix all this, so I'll be sending a PR in soon.
