Subject: libssh-0.11.1 fails to cross compile
Date: Thu, 24 Apr 2025 09:21:17 +0200 (CEST)

Hello,

Since commit b12d44dd5e35ac236bf3fbb5619b9c8c2f42c902 turned on tests and switchted to gexps the package no longer cross compiles, which is a dependency of guile-ssh (and guix).

When cross compiling to a 32bit target (tested with i586-pc-gnu) something goes wrong ungexp-splicing the extra CFLAGS and the literal list procedure is inserted for the cflags:

starting phase `configure'
source directory: "/tmp/guix-build-libssh-0.11.1.drv-0/libssh-0.11.1" (relative from build: "../libssh-0.11.1")
build directory: "/tmp/guix-build-libssh-0.11.1.drv-0/build"
running 'cmake' with arguments ("../libssh-0.11.1" "-DCMAKE_BUILD_TYPE=RelWithDebInfo" "-DCMAKE_INSTALL_PREFIX=/gnu/store/q1zi25van8xrzmi7gmj28rw8q9cwx7s1-libssh-0.11.1" "-DCMAKE_INSTALL_LIBDIR=lib" "-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE" "-DCMAKE_INSTALL_RPATH=/gnu/store/q1zi25van8xrzmi7gmj28rw8q9cwx7s1-libssh-0.11.1/lib" "-DCMAKE_VERBOSE_MAKEFILE=ON" "-DCMAKE_C_COMPILER=i586-pc-gnu-gcc" "-DCMAKE_CXX_COMPILER=i586-pc-gnu-g++" "-DCMAKE_SYSTEM_NAME=GNU" "-DWITH_GCRYPT=ON" "-DUNIT_TESTING=ON" #<procedure list _> "-DCMAKE_C_FLAGS=-g -O2 -Wno-incompatible-pointer-types")
error: in phase 'configure': uncaught exception:
wrong-type-arg #f "Wrong type (expecting ~A): ~S" ("string" #<procedure list _>) (#<procedure list _>) 


Even a 64bit target (tested with aarch64-linux-gnu) fails because it cant find cmocka but i assume the tests can not be run when cross compiling anyway?

There is also a deperecation warning for the gcrypt backend

Thanks.

Fixed:

  93f61013db gnu: libssh: Restore support for cross-compilation.
  f88be0a5b3 gnu: libssh: Fix #:configure-flags for cross-compilation to 32-bit.

Someday we’ll get childhurd support for more than two days in a row.
:-)

Thanks,
Ludo’.
