QMake error on Ubuntu 18.04: Project ERROR: quazip could not be found.

What am I missing?

I'm trying to build 0.9.10 from the GitHub repo, under Ubuntu 18.04 (amd64).

[cjmayo]

Two points with the current build system:

• It is only looking for QuaZIP in a specific directory
• It is looking for QuaZIP 1.x

For the first point, I suggest supporting pkg-config #3993 - but looks that will only work with Ubuntu 23.04 onwards when libquazip1-qt5-dev becomes available in Ubuntu:
https://packages.ubuntu.com/search?keywords=libquazip1-qt5-dev&searchon=names&suite=all&section=all

To actually try and answer the question. If QuaZIP 0.7 still works with v0.9.10, may be possible to modify pri/quazipdetect.pri to find the 18.04 version something like (untested) :

--- a/pri/quazipdetect.pri

OK, I will try that. At Thu, 15 Dec 2022 11:49:09 -0800 fritzing/fritzing-app ***@***.***> wrote:

I'd suggest to install libquazip from source. It is not that big.

[Splarkszter]

Seems quazip it's required but wasn't on my system, I didn't find it on the installation instructions tho.

I did $ sudo apt-get install libquazip5-dev but I still get quazip not found error for the qmake for fritzing-app

I'm on Linux Mint 21.1

Edit: Using the modified script I got past that error. Running make, I had the package libngspice0-dev missing, so I installed it, and finally I could build fritzing. BUT seems it kept building until it reached quazip.h and says that there is no such file. That's unfortunate.
