Hi, I am a newcomer in macOS development, and I am struggling to create a package with the XCode command line tools that is installable on other computers. In its minimal version, the package shall install a simple program to usr/local/: hello.c: #include <stdio.h> int main(void) { printf("Hello World\n"); return 0; } distribution.plist: <installer-gui-script minSpecVersion="1"> <product id="net.world" version="1.0"/> <title>Hello World</title> <choices-outline> <line choice="net.world.hello"/> </choices-outline> <choice id="net.world.hello" title="Hello"> <pkg-ref id="net.world.hello">h1.pkg</pkg-ref> </choice> </installer-gui-script> build.sh: #!/bin/sh cc -o hello hello.c mkdir -p local/bin cp hello local/bin/ codesign -s - -i net.world.hello local/bin/hello pkgbuild --identifier net.world.hello \ --root local \ --install-location /usr/local \ h1.pkg productbuild --distribution distribution.plist --resources . hello.pkg The build scrips produces a package hello.pkg. However, when I try to install it, I get <Debug>: Product archive /Users/foo/hello.pkg trustLevel=100 <Error>: PKInstallRequest: failed to initialize. Error: Error Domain=PKInstallRequestErrorDomain Code=2 "Specifier Description:<PKPackageSpecifier>: { URL = "file:///Users/foo/h1.pkg"; identifier = "net.world.hello"; options = 0; version = 0; }" UserInfo={NSLocalizedFailureReason=Specifier Description:<PKPackageSpecifier>: { URL = "file:///Users/foo/h1.pkg"; identifier = "net.world.hello"; options = 0; version = 0; }} <Debug>: External component packages (1) trustLevel=100 (trust evaluation failed) <Debug>: -[IFDInstallController(Private) _buildInstallPlanReturningError:]: location = file://localhost <Debug>: -[IFDInstallController(Private) _buildInstallPlanReturningError:]: file://localhost/Users/foo/h1.pkg <Error>: Failed to locate package at path /Users/foo/h1.pkg (h1.pkg -- file://localhost/Users/foo/hello.pkg) <Error>: Install failed: The Installer can’t locate the data it needs to install the software. Check your install media or internet connection and try again, or contact the software manufacturer for assistance. The package build runs on Github Action (macOS 11/Xcode 13.2). What is wrong with this setup, and how can I create a distributable package that installs in /usr/local/?

I want to distribute a program that installs its own terminfo file. Usually, these files go to /usr/share/terminfo (for all users) resp. ~/.terminfo (for one user). However, it turns out that writing the/usr/share/terminfo is restricted and not possible during a regular package installation. And ~/.terminfo is user specific and not suitable for programs that are installed for all users. Trying out /usr/local/share/terminfo didn't work; it would require for the user to set the environment variable TERMINFO before start. Is there a local, standard directory available that could be used here?
