Describe the bug Compiler is not implemented: '' or 'AppleClang'

Expected behavior It to be implemented

To Reproduce

CMakeLists.txt

cmake_minimum_required(VERSION 3.2)
project(pp VERSION 0.0.0 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 14)
set(src src/main.cpp)

find_package(SW REQUIRED)
sw_add_package(org.sw.demo.ocornut.imgui)
sw_execute()

add_executable(${PROJECT_NAME} ${src})
target_link_libraries(${PROJECT_NAME} PRIVATE org.sw.demo.ocornut.imgui)

sh

$ mkdir build src
$ curl -L https://raw.githubusercontent.com/ocornut/imgui/6a161b8/examples/example_allegro5/main.cpp -o src/main.cpp
$ cd build && cmake ..

Hi,

I've implemented a fix. Run sudo sw --self-upgrade and re-run cmake again.

[SamuelMarks]

Thanks @egorpugin but that didn't do anything. I'm trying a sw build -static of sw itself now, but don't have enough free space so am working on clearing that up.

[egorpugin]

You need to update sw client. Try sw --version. It should tell some today's time. Maybe cmake uses old sw copy?

[SamuelMarks]

Yeah it's weird, I wasn't using sudo before now with sudo and after deleting and recreating the build dir I get a Could NOT find SW (missing: SW_EXECUTABLE) error, but on the shell sw still works, and with --version gives:

sw.client.sw version 1.0.0

[egorpugin]

Run sw setup to make sw visible for cmake. (Probably remove cmake cache as well.)

[SamuelMarks]

Hmm, same error still. Just had to do one runaround on permissions to solve the is executable but not readable. CMake is ignoring it for compatibility. using chmod

[egorpugin]

Looks like I forget to bump cmake script version. https://github.com/SoftwareNetwork/sw/commit/d947222bd478c72865471c82fc05229d4cb2627d I'll upload new binaries.

[egorpugin]

Try now.

sudo sw --self-upgrade
sw setup
(cmake command, clear cmake cache)

[SamuelMarks]

Same error. Even after deleting my build dir and remaking it.

$ sw --version

Try to find ~/.cmake/packages/ ... SWConfig.cmake and check if that file is updated with commits https://github.com/SoftwareNetwork/sw/commit/ef77960d6576e9055df39e95a3c025e00e584d61 https://github.com/SoftwareNetwork/sw/commit/d947222bd478c72865471c82fc05229d4cb2627d

Maybe try to run sudo sw setup.

[SamuelMarks]

No dice:

/tmp/imgui3 $ sudo sw setup
/tmp/imgui3 $ sw setup
/tmp/imgui3 $ rm -rf ~/.cmake
/tmp/imgui3 $ rm -rf build && mkdir build && cd $_
/tmp/imgui3/build $ cmake ..

  By not providing "FindSW.cmake" in CMAKE_MODULE_PATH this project has asked

  Could not find a package configuration file provided by "SW" with any of

  Add the installation prefix of "SW" to CMAKE_PREFIX_PATH or set "SW_DIR" to
  a directory containing one of the above files.  If "SW" provides a separate
  development package or SDK, be sure it has been installed.

[egorpugin]

Run sw setup after removing .cmake. It setups those files.

[SamuelMarks]

Yes just did that still same error:

[egorpugin]

Can you try to add this change manually? https://github.com/SoftwareNetwork/sw/commit/ef77960d6576e9055df39e95a3c025e00e584d61

[SamuelMarks]

Same error after:

$ curl -L https://raw.githubusercontent.com/SoftwareNetwork/sw/ef77960d6576e9055df39e95a3c025e00e584d61/src/sw/client/common/inserts/SWConfig.cmake -o ~/.cmake/packages/SWConfig.cmake
$ sudo sw setup
$ sw setup
$ rm -rf build && mkdir build && cd $_
$ cmake ..

EDIT: Same error if I do the curl line after sw setup

[egorpugin]

You are copying old version, not new. Copy the file from this commit. https://github.com/SoftwareNetwork/sw/commit/d947222bd478c72865471c82fc05229d4cb2627d

[SamuelMarks]

@egorpugin Same error. Tried with d947222bd478c72865471c82fc05229d4cb2627d instead of ef77960d6576e9055df39e95a3c025e00e584d61. Tried with sw setup before and after the curl line (ensuring to remove and remake the build dir each time). To no avail.

[egorpugin]

Ok, found the issue. "AppleClang" must be "APPLECLANG"

[egorpugin]

I've updated binaries. sudo sw --self-upgrade

[SamuelMarks]

Thanks, that worked, now back to my incomplete type errors (see https://github.com/SoftwareNetwork/sw/issues/65)
