Hi
I am a new user of CMake (literally day one) and everything has gone swimmingly so far except for one thing - I am getting an error when use file(ARCHIVE_EXTRACT). I am guessing it is something pretty obvious, but if someone could point me in the right direction I would be most grateful.
I can demo the problem very simply with the following CMakeLists.txt: (Note I have really stripped this down to the bare minimum!)
cmake_minimum_required(VERSION 3.25)
project(arctest VERSION 1.0 DESCRIPTION “Archive Extract test” LANGUAGES C CXX)
file(ARCHIVE_EXTRACT INPUT “test.tar.gz”)
The “test.tar.gz” file is a simple archive with a couple of text files in it, created using “tar -czvf …”
When I run “cmake -B build” I get the following error:
CMake Error: Problem with archive_read_open_file(): Failed to open ‘test.tar.gz’
CMake Error at CMakeLists.txt:3 (file):
file failed to extract: test.tar.gz
However, if I change line 3 of the CMakeLists file to
file(ARCHIVE_EXTRACT INPUT “test.tar.gz” LIST_ONLY)
it completes fine - listing the files in the archive.
BTW the system I am running on is fully updated Ubuntu and CMake 3.28.3
Best regards
