Compilation error on arch linux

[pietroiusti]

I get this error when (following the readme and) running make on arch linux. I had no problem on Ubuntu. Thanks.

I manage to compile if I replace all occurrences of ${CMAKE_THREAD_LIBS_INIT} with ${CMAKE_THREAD_LIBS_INIT} ${HAVE_PAPER_H}, both in xpdf-qt/CMakeLists.txt and xpdf/CMakeLists.txt as done in kermitt2/xpdf-4.00#1 (comment)

[lfoppiano]

I'm closing this issue, seems quite old. Feel free to reopen, should the problem be still there.

[kermitt2]

Re-opening because the forks for xpdf-4.03 and later need to be reviewed for this problem, based on the fixed made for xpdf-4.00 (which might have been forgotten to be added to the xpdf-4.03 fork).

[lfoppiano]

Sorry 😅 I was too generous with the close button.

I went through the changes and patches to the code mentioned in this and the linked comment are commented out in both 4.0.0 and 4.03 (changes in 2021)

@pietroiusti could you perhaps give it a try with the current master version just to check whether the issue still happens?
