generated libpcap.pc file format error

generated libpcap.pc file syntax error

example:

#
# pkg-config file for libpcap.
#
# These variables come from the configure script, so includedir and
# libdir may be defined in terms of prefix and exec_prefix, so the
# latter must be defined as well.
#
prefix="/data/data/com.termux/files/home/.ndk-pkg/install.d/libpcap/arm64-v8a"
exec_prefix="${prefix}"
includedir="${prefix}/include"
libdir="${exec_prefix}/lib"

Name: libpcap
Description: Platform-independent network traffic capture library
Version: 1.10.1
Libs: -L${libdir} -lpcap  -l/data/data/com.termux/files/home/.ndk-pkg/install.d/openssl/arm64-v8a/lib/libssl.so -l/data/data/com.termux/files/home/.ndk-pkg/install.d/openssl/arm64-v8a/lib/libcrypto.so
Cflags: -I${includedir}

-l/data/data/com.termux/files/home/.ndk-pkg/install.d/openssl/arm64-v8a/lib/libssl.so

-l argument can not follow the fullpath of library.

Thank you for this bug report. Could you tell which libpcap version you are using and provide exact steps to reproduce?

https://www.tcpdump.org/release/libpcap-1.10.1.tar.gz

reproduce steps:

cmake -B build.d -S . -DCMAKE_INSTALL_PREFIX=./output
cmake --build   build.d
cmake --install build.d

relavent code:

https://github.com/the-tcpdump-group/libpcap/blob/master/CMakeLists.txt#L1053

https://github.com/the-tcpdump-group/libpcap/blob/master/CMakeLists.txt#L2735-L2737

OPENSSL_LIBRARIES is fullpath

[infrastation]

This is what I get with CMake on Linux:

Libs: -L${libdir} -lpcap
Libs.private:  -libverbs -lnl-3 -l/usr/lib/x86_64-linux-gnu/libssl.so -l/usr/lib/x86_64-linux-gnu/libcrypto.so -l/usr/lib/x86_64-linux-gnu/libdbus-1.so

And with Autoconf:

Libs: -L${libdir} -lpcap
Libs.private: -libverbs -lnl-genl-3 -lnl-3  -ldbus-1

This should be fixed by 6493919a4c7cf15d3d4f9878b2f290dd36efafc0.

This should be fixed by [6493919]

Will this commit be backported to the git branch libpcap-1.10?

[guyharris]

Will this commit be backported to the git branch libpcap-1.10?

Yes, I backported the configuration fixes from the main branch to the 1.10 branch.

[fxlb]

OK. I backported the "configure: use pcap-config --static-pcap-only if available." tcpdump related commit from the main branch to tcpdump-4.99 branch.
