Re: net/freerdp2 missing build dependency on python27 via gnome-doc-utils/py-xslt

["Morgan, Iain (ARC-TN)[InuTeq, LLC]" <iain.morgan%nasa.gov@localhost>]

Hi,

I just came across this post while searching for any discussion on this textproc/gnome-doc-utils issue. I don't see that there was any response and the issue is still present in the 2020Q4 release.

In my case, the problem is triggered by building biology/bioperl. Among its many dependencies, it eventually pulls in textproc/gnome-doc-utils and the same problem ensues.

The workaround is to ensure that lang/python27 is already installed, but pkgsrc should really just handle this automatically.

    Shouldn't be gnome-doc-utils to be using python37 already? Other 
    projects
    switched already and seems to be running fine.

    anyway tried these changes......

    /usr/pkgsrc/textproc/gnome-doc-utils
    PYTHON_VERSIONS_ACCEPTED=       37 # py-libxslt

    then py-libxslt fail with:


    => Full dependency py37-libxml2>=2.6.16: found py37-libxml2-2.9.10nb2
    => Full dependency py37-libxslt>=1.1.12: NOT found
    => Verifying reinstall for ../../textproc/py-libxslt
    ERROR: This package has set PKG_FAIL_REASON:
    ERROR: No valid Python version
    *** Error code 1

    so changed
    /usr/pkgsrc/textproc/py-libxslt
    PYTHON_VERSIONS_ACCEPTED=       37

    howere rerun make after cleanup ends with:

    failed to generate stubs for libxslt, aborting...
    Traceback (most recent call last):
       File "setup.py", line 68, in <module>
         import generator
       File

                     ^
    SyntaxError: Missing parentheses in call to 'print'. Did you mean 
    print("close")?

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
       File "setup.py", line 71, in <module>
         print(sys.exc_type, sys.exc_value)
    AttributeError: module 'sys' has no attribute 'exc_type'

    the I found about /usr/pkgsrc/lang/python/pyversion.mk so reverted back
    and went to pkgsrc guide :-)

    There I found 
    https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.netbsd.org%2Fdocs%2Fpkgsrc%2Fcreating.html%23creating.python-module&amp;data=04%7C01%7Ciain.morgan%40nasa.gov%7Cc15bf935d59b4b5ffbcd08d88eb5a503%7C7005d45845be48ae8140d43da96dd17b%7C0%7C1%7C637416258090780996%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=7gWKLn8nI0fD1vRFGzSzlllhG00bDpUHJ6jfEo9nRRA%3D&amp;reserved=0
    and so set:

    PYTHON_VERSIONS_INCOMPATIBLE=       37

    in /usr/pkgsrc/textproc/py-xslt/Makefile

    and now is all fine and freerdp2 build properly. I know it is quick and 
    dirty change
    so can't tell if this can be accepted as a change in pkgsrc

    $ xfreerdp2 /version
    This is FreeRDP version 2.1.2 (2.1.2)
