error adding symbols: Malformed archive

[JoseQuintas]

problem occurs when png is before anothers libraries
but libs=png is on hbwin.hbc, and hbwin do not use it
correct is include it on hbhpdf.hbc, because harupdf need png.
if it is for windows only, this can be indicated using {win}libs=png
This will reduce problems.
On my recent test:
hbmk2 test gtwvg.hbc -> ok
hbmk2 gtwvg.hbc test -> error
because gtwvg.hbc have hbwin.hbc, and hbwin.hbc have libs=png

I do not know about C source code.
Is it possible that PNG and harupdf are directly dependant ?
If yes, may be it is related to how they are on link order.
And this another reason to do not include libs=png on hbwin.hbc, because nested hbc can include hbwin.hbc and change order, this is not visible on HBP.

I copy src/3rd/png from 3.4 to 3.2 and all ok.
I do not know about C, I do not know if change is valid, but it works.

[tuffnatty]

@JoseQuintas src/3rd/png has been updated in this repo, please report if the issue is still valid.

[JoseQuintas]

It is already made.

[JoseQuintas]

I was wrong. There are changes but problem is not solved.
Receive the error message just now. Solve on same way, copying from 3.4
