Any ideas?
Thanks,

Thank you for this feedback.
Could send the output of this command :

uname -i

[Aazhar]

you need to generate build file using the flag PIC as showed in the error.
So you need to run cmake this way :

cmake "-DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true" .

[rytis-paskauskas]

Sorry but this didn't work for me: $ make clean; $ cmake "-DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true" ./; make ....

Thanks for the information,
I can't reproduce this error in my environment, but I think you need to regenerate the libpng.a.
To do so you to go under libs/image/png/src and run :

cmake "-DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true" ./; make

This will generate a libpng.a file that you need to copy under libs/image/png/linux , since I understand you are using linux.

Please keep me informed.

[rytis-paskauskas]

It appears your suggestion was correct. I can't see the libpng errors anymore but there are still many similar errors from the other libs: [15%] Linking CXX executable pdfalto /usr/bin/ld: libs/libxml/linux/libxml2.a(entities.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC ... I couldn't apply the same fix to the remaining libs as the other sources aren't available.

Could you update your repository and re make it.

[rytis-paskauskas]

Back to square one I'm afraid. I compiled the libpng and libzlib with your earlier flag suggestion. Here is the full error message.

Ok, it seems that your linker is old.
Could you send the output of this

ld -v

[Aazhar]

What I suggest is you checkout the last updates and you compile the dependencies following the description here : https://github.com/kermitt2/pdfalto/blob/master/Dependencies_INSTALL.md

[rytis-paskauskas]

$ ld -v
GNU ld (GNU Binutils) 2.31.1

I think you'll agree that my linker is not 'old'.

Thanks for writing up the 'do it yourself' instructions even though the approach is hardly ideal to solve one's software's portability issues.

[Aazhar]

I've a bash script for installing the dependencies in one step , you can recompile all of the dependencies using this bash script https://github.com/kermitt2/pdfalto/blob/master/install_deps.sh
