Arch Linux User Repository

I ran into the same issue as emulti. Their solution fixed it, thanks! 🙂

Do you really need the -git variant of libdeltachat as dependency?

Just depending on libdeltachat and not libdeltachat-git gives the user freedom of choice which package to install. (↗ libdeltachat-git currently does not build.)

I just tried compilation with libdeltachat, and it works.

Please change the dependency libdeltachat-git to libdeltachat.

You need to add -fpermissive to $CXXFLAGS/ $CFLAGS, otherwise build fails (for me) with accounts.cpp:10:63: error: invalid conversion from ‘const char*’ to ‘int’ [-fpermissive]:

/tmp/makepkg/build/kdeltachat-git/src/kdeltachat/accounts.cpp: In constructor ‘DcAccounts::DcAccounts(QObject*)’:
/tmp/makepkg/build/kdeltachat-git/src/kdeltachat/accounts.cpp:10:63: error: invalid conversion from ‘const char*’ to ‘int’ [-fpermissive]
   10 |     m_accounts = dc_accounts_new("Qt", path.toUtf8().constData());
      |                                        ~~~~~~~~~~~~~~~~~~~~~~~^~
      |                                                               |
      |                                                               const char*

A solution is to add the following to build():

  CXXFLAGS+=' -fpermissive'
  export CXXFLAGS
  CFLAGS+=' -fpermissive'
  export CFLAGS

Regards and thans for maintaining!

@emulti I just bumped release of kdeltachat since there is an updated version of libdeltachat-git. No issues during compiling, though. This is a list of all qt packages installed on my system:

However, building kDeltaChat on this system gives the following error, plus a warning:

There don't seem to be qt6-quickcontrols[*] packages for Arch like there are for qt5.

What can I try? Is it possible to force Cmake to build using Qt5?

To answer my own question:

makepkg -o

then remove the reference to Qt6 from

find_package(
  QT NAMES Qt6 Qt5

in line 19 of CMakelists.txt

then

makepkg -se

Builds correctly.

@MightyPork Are you sure? I removed sqlcipher from my system and kdeltachat compiles fine.

build failed with = note: /usr/bin/ld: cannot find -lsqlcipher

some dependency missing?

@polpetta I can't reproduce your error. It just compiled fine right now but I have not any qt6 package. Maybe the compiler want to use qt 6 if it finds some qt6-* package installed?

Can you try again removing any application from this output pacman -Q | grep qt6?

@gcala, the build fails on my system, it is asking for qt6-webengine (that I've installed btw). The error I get is the following:
