llbuild: 'sqlite3.h' file not found about swift-llbuild HOT 5 OPEN

How are you invoking swift build? You should be passing the header search path or ensuring that the systemLibrary dependency is set up with the right paths.

How are you invoking swift build?

Via SwiftPM bootstrap rather than llbuild directly.

the systemLibrary dependency

Where is this dependency located? SQLite3 seems to only be passed as a linker flag here:

It should be able to pick up the pkg-config like the CMake part of the build is able to.

Issue seems to just be #733 again but s/OpenBSD/any other non-usr install/

Reproduction steps:

$ docker run --rm -it swift:5.9.2
# apt update
# apt install g++ make cmake curl
# cd /root
# curl -LO https://www.sqlite.org/2024/sqlite-autoconf-3450100.tar.gz
# tar xf sqlite-autoconf-3450100.tar.gz
# cd sqlite-autoconf-3450100
# ./configure --prefix=/opt/prefix
# make install
# cd ..
# export PKG_CONFIG_PATH=/opt/prefix/lib/pkgconfig
# pkg-config --cflags sqlite3
-I/opt/prefix/include
# git clone https://github.com/apple/swift-package-manager
# cd swift-package-manager
# git checkout swift-5.9.2-RELEASE
# swift build

I ran another test in that linked 5.9.2 pull and I think he is right that llbuild should specify the systemLibrary dependency explicitly in Package.swift, or it fails for any non-standard directory where it may be installed, such as when cross-compiling.

I'm guessing he could make this more explicit by trying to build the llbuild package alone with SwiftPM in his example above and that would also fail, as the Swift toolchain build avoids that by building llbuild alone with CMake, obviously since SwiftPM isn't built yet when first building llbuild alone in the toolchain build.
