Build fails on Debian Jessie #384

mlocati · 2021-07-01T07:24:46Z

It seems that cmark 0.30.0 can't be compiled on Debian Jessie (compilation of cmark 0.29.0 succeeds):

PS:

$ cmake --version
cmake version 3.0.2

nwellnhof · 2021-07-01T15:26:34Z

COMPILE_LANGUAGE requires CMake 3.3, so cmake_minimum_required should be updated.

jgm · 2021-07-01T17:46:49Z

OK, let's at least do that. But is it worth thinking about removing this 3.3 only feature instead, to make it more compatible? Does anyone know what the alternative would be?
(This was part of cmake changes submitted by @compnerd -- who might be able to comment on this.)

jgm · 2021-07-01T17:47:32Z

Btw jessie is oldoldstable, under "extended LTS" support. It wouldn't be crazy to expect people running such an old system to install a more recent cmake, but still, compatibility is good if we can achieve it.

nwellnhof · 2021-07-01T17:55:08Z

I'm not sure why $<COMPILE_LANGUAGE:C> is needed at all. Shouldn't the language always be C?

compnerd · 2021-07-01T18:38:48Z

The generator expression for the language is to deal with the Swift build system (that definitely does not do the right thing in many ways). Unfortunately, cleaning that up has been slow going. So, at least for the Swift project, the generator expressions are needed.

jgm · 2021-07-02T16:22:04Z

Is there a way to work around the issue in cmake without using the newer feature COMPILE_LANGUAGE?

compnerd · 2021-07-02T16:31:20Z

I think that the way to do that would to not use any add_compile_options at all, and instead explicitly set the options on all the targets via target_compile_options. You could add a function/macro to centralize that if there are too many targets.

jgm · 2021-07-02T16:38:53Z

If this would work and not add too much complexity, I think it would be desirable to make the project buildable on older systems. However, I don't know much about cmake and wouldn't be able to make these changes myself. Any interest in doing a PR?

It's either this or changing the required cmake_version.

compnerd · 2021-07-06T17:26:56Z

I think I can take a stab at it and upload a potential change that can restore the build on older versions.

The `COMPILE_LANGUAGE` generator expression was introduced in CMake 3.3. Debian Jessie has an older CMake version bundled, which prevents building on that platform without manually building CMake. This uses a more error-prone mechanism of requiring the commonmark developer to explicitly invoke `cmark_add_compile_options` on the target to ensure that the flags are propagated for the targets without using the generator expression. Adding the options unconditionally prevents using CMark in a build with a non-C programming language. Fixes: commonmark#384

Adding the options unconditionally prevents using CMark in a build with a non-C programming language. Fixes: #384

Changelog: Properly indent block-level contents of list items in man (openembedded#258). commonmark/cmark#258 This handles nested lists as well as items with multiple paragraphs. The change requires addition of a new field block_number_in_list_item to cmark_renderer, but this does not change the public API. Fix quadratic behavior when parsing emphasis (openembedded#389, Nick Wellnhofer). Delimiters can be deleted, so store delimiter positions instead of pointers in openers_bottom. Besides causing undefined behavior when reading a dangling pointer, this could also result in quadratic behavior when parsing emphasis. commonmark/cmark#389 Fix quadratic behavior when parsing smart quotes (openembedded#388, Nick Wellnhofer). Remove matching smart quote delimiters. Otherwise, the same opener could be found over and over, preventing the openers_bottom optimization from kicking in and leading to quadratic behavior when processing lots of quotes. commonmark/cmark#388 Modify CMake configuration so that the project can be built with older versions of CMake (openembedded#384, Saleem Abdulrasool). (In 0.30.0, some features were used that require CMake >= 3.3.) The cost of this backwards compatibility is that developers must now explicitly invoke cmark_add_compile_options when a new compilation target is added. commonmark/cmark#384 Remove a comma at the end of an enumerator list, which was flagged by clang as a C++11 extension. make_man_page.py: use absolute path with CDLL. This avoids the error "file system relative paths not allowed in hardened programs." Include cmark version in cmark(3) man page (instead of LOCAL).

It seems that #385 isn't enough.

@compnerd can you see what the problem is here?

compnerd · 2021-08-04T21:51:06Z

Unfortunately not. Could you please provide the resulting Makefile with the f invalid output? That might help figure out what happens, but I'm not convinced that this is really the same issue anymore.

mlocati · 2021-08-04T21:57:04Z

@compnerd do you mean src/CMakeFiles/cmark_static.dir/build.make?

compnerd · 2021-08-05T00:54:42Z

@mlocati yes, as I cannot tell what the rule is that it is having trouble with.

mlocati · 2021-08-05T06:13:55Z

@compnerd Here it is: build.make.zip

compnerd · 2021-08-12T01:02:38Z

Interesting:

src/libcmark$<$<BOOL:>:_static>.a: src/CMakeFiles/cmark_static.dir/cmark.c.o

Seems like the property is the output name: https://github.com/commonmark/cmark/blob/master/src/CMakeLists.txt#L101

I can try to whip up a patch, but wont be able to test it. Would you mind testing it @mlocati?

mlocati · 2021-08-12T16:17:52Z

@compnerd Sure! With docker, testing it is a breeze

compnerd · 2021-08-13T23:03:45Z

#392 should hopefully fix the build for you @mlocati

Changelog: Properly indent block-level contents of list items in man (#258). commonmark/cmark#258 This handles nested lists as well as items with multiple paragraphs. The change requires addition of a new field block_number_in_list_item to cmark_renderer, but this does not change the public API. Fix quadratic behavior when parsing emphasis (#389, Nick Wellnhofer). Delimiters can be deleted, so store delimiter positions instead of pointers in openers_bottom. Besides causing undefined behavior when reading a dangling pointer, this could also result in quadratic behavior when parsing emphasis. commonmark/cmark#389 Fix quadratic behavior when parsing smart quotes (#388, Nick Wellnhofer). Remove matching smart quote delimiters. Otherwise, the same opener could be found over and over, preventing the openers_bottom optimization from kicking in and leading to quadratic behavior when processing lots of quotes. commonmark/cmark#388 Modify CMake configuration so that the project can be built with older versions of CMake (#384, Saleem Abdulrasool). (In 0.30.0, some features were used that require CMake >= 3.3.) The cost of this backwards compatibility is that developers must now explicitly invoke cmark_add_compile_options when a new compilation target is added. commonmark/cmark#384 Remove a comma at the end of an enumerator list, which was flagged by clang as a C++11 extension. make_man_page.py: use absolute path with CDLL. This avoids the error "file system relative paths not allowed in hardened programs." Include cmark version in cmark(3) man page (instead of LOCAL).
