How to solve a missing pkg-config command

[a.burks]

Thanks for your response. I appreciate the time you have invested.

I'm working on macOS 10.13.1 High Sierra and Qt Creator 4.2.1 (Sailfish OS SDK 1710) based on Qt 5.6.2 (Clang 6.0 (Apple), 64 bit).

I did run an update yesterday with the maintenance tool. But the problem occured in the last versios, either. So far I relized, the maintenance tool replaces the existing installation for a major update.

I also tried to clean the project and to close and restart Qt Creator. I assume, that the library pkg-config is linked to the wrong path somewhere. But I don't know, where the library is linked, in the Qt Creator itself or in the project. It is also possible that the library is missed on the virtual machine for thebuild process, that is included in the SDK for SailfishOS.

Hi,

You can use something like macports or brew to install additional tools that might be missing.

I did have the same idea. Unfortunately the package seems to exist already:

Warning: pkg-config 0.29.2 is already installed, it's just not linked.
You can use `brew link pkg-config` to link this version.

I did run the command, but there is a conflict:

Error: Could not symlink bin/pkg-config
Target /usr/local/bin/pkg-config
already exists. You may want to remove it:
  rm '/usr/local/bin/pkg-config'

To force the link and overwrite all conflicting files:
  brew link --overwrite pkg-config

To list all files that would be deleted:
  brew link --overwrite --dry-run pkg-config

The list of the last command:

Would remove:
/usr/local/bin/pkg-config
/usr/local/share/aclocal/pkg.m4
/usr/local/share/doc/pkg-config/pkg-config-guide.html
/usr/local/share/man/man1/pkg-config.1

It seems that Qt Creator or the project - I don't know - expects the pkg-config in a different path namely /bin/sh.

I also don't know, whether QT Creator of the SailfishOS SDK expects or the project itself expects pkg-config on my host, where Qt Creator is installed, or on the build engine on the virtual machine.

I would appreciate any help.

The /bin/sh part refers to the bash interpreter used to call pkg-config.

I don't know, I haven't used that SDK at all. Where to you see that message printed ?

Hi @a-burks

i was facing one similar problem with pkg-config, with one qt project (i am not sure , but maybe it is the same problem for you)

and for me the problem was due to missing build var environment in Qt Creator

So to solve this problem i have added pkg-config path with this following steps:

1. From Qt creator , go to project mode.
2. In build environment add var:

PKG_CONFIG_PATH

And for the value of this variable , you have to add the path to pkgconfig, i think that in your case this should be equal to :

/usr/local/bin/pkg-config

Are you having this error only with one qt project? or with all qt project?

@mostefa Thanks for the recommendation. This is my configuration, I've checked:

I'm afraid, that the parameter is ignored. I get the same error message:

/bin/sh: pkg-config: command not found

Your screenshot is not visible ?

[a.burks]

@mostefa Yes, the file was too large. Now it should be visible.

From a quick search on stackoverflow , i think that you are facing this problem too

https://stackoverflow.com/a/20805469

Can you try then to add

PKG_CONFIG = /usr/local/bin/pkg-config

Inside your .pro?

[a.burks]

@mostefa Unfortunately this has no impact. I get the same output. This is, how the *.pro file looks like:

TEMPLATE = subdirs
SUBDIRS += src plugin tools tests doc

plugin.depends = src
tools.depends = src
tests.depends = src

PKG_CONFIG = /usr/local/bin/pkg-config

QMAKE_CLEAN += \
    build-stamp \
    configure-stamp \
    artifacts/*.deb \
    *.log.xml \
    *.log

QMAKE_DISTCLEAN += \
    build-stamp \
    configure-stamp \
    *.log.xml \
    *.log

PKG_CONFIG = /usr/local/bin/pkg-config

The output is still the following:

/bin/sh: pkg-config: command not found

I posted the issue in GitHib. Unfortunately I can't understand the answer. Can someone help?

Building a Mer/Sailfish OS project within Qt Creator relies on the definition and use of qtc_* macros inside the .spec file, which is not the case of lipstick library. Opened #122 to let mb2 issue warning when qtc_* macros are not used in the .spec file.
