<!-- Please report new issues at https://inkscape.org/report; this tracker is for staff-confirmed issues only. See our full bug reporting guidelines at https://inkscape.org/contribute/report-bugs/ --> #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> - Upgrade GNU/Linux from **poppler-25.05.0** to **poppler-25.06.0** - Recompile *Inkscape-1.4.2* to build against the new poppler. #### What happened? Inkscape fails to build from source. It seems that Poppler 25.06 changed some *C*-like structures to *C++*, notably `std::unique_ptr` and `std::vector`. Perhaps @KrIr17 would like to take a look? Seems to be an expert in fixing poppler. :smiley: #### Inkscape Version and Operating System: - Inkscape Version: 1.4.2 - Operating System: Slackware Linux - Operating System version: 64-current - Compiler: GNU gcc/g++ version *14.3.0* #### Error output during compile: ``` [ 16%] Building CXX object src/CMakeFiles/inkscape_base.dir/extension/internal/pdfinput/pdf-parser.cpp.o /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp: In member function ‘void PdfParser::opSetExtGState(Object*, int)’: /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:753:28: error: cannot convert ‘Function* [4]’ to ‘std::vector<std::unique_ptr<Function> >’ 753 | state->setTransfer(funcs); | ^~~~~ | | | Function* [4] In file included from /usr/include/poppler/Gfx.h:40, from /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.h:37, from /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:19: /usr/include/poppler/GfxState.h:1633:61: note: initializing argument 1 of ‘void GfxState::setTransfer(std::vector<std::unique_ptr<Function> >)’ 1633 | void setTransfer(std::vector<std::unique_ptr<Function>> funcs); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~ /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:758:39: error: cannot convert ‘std::unique_ptr<Function>’ to ‘Function*’ in assignment 758 | funcs[i] = Function::parse(&obj3); | ~~~~~~~~~~~~~~~^~~~~~~ | | | std::unique_ptr<Function> /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:766:32: error: cannot convert ‘Function* [4]’ to ‘std::vector<std::unique_ptr<Function> >’ 766 | state->setTransfer(funcs); | ^~~~~ | | | Function* [4] /usr/include/poppler/GfxState.h:1633:61: note: initializing argument 1 of ‘void GfxState::setTransfer(std::vector<std::unique_ptr<Function> >)’ 1633 | void setTransfer(std::vector<std::unique_ptr<Function>> funcs); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~ /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:769:40: error: cannot convert ‘std::unique_ptr<Function>’ to ‘Function*’ in assignment 769 | if ((funcs[0] = Function::parse(&obj2))) { | ~~~~~~~~~~~~~~~^~~~~~~ | | | std::unique_ptr<Function> /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:771:32: error: cannot convert ‘Function* [4]’ to ‘std::vector<std::unique_ptr<Function> >’ 771 | state->setTransfer(funcs); | ^~~~~ | | | Function* [4] /usr/include/poppler/GfxState.h:1633:61: note: initializing argument 1 of ‘void GfxState::setTransfer(std::vector<std::unique_ptr<Function> >)’ 1633 | void setTransfer(std::vector<std::unique_ptr<Function>> funcs); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~ /tmp/slackbuild/inkscape/inkscape-1.4.2/src/extension/internal/pdfinput/pdf-parser.cpp:790:43: error: cannot convert ‘std::unique_ptr<Function>’ to ‘Function*’ in assignment 790 | funcs[0] = Function::parse(&obj3); | ~~~~~~~~~~~~~~~^~~~~~~ | | | std::unique_ptr<Function> make[2]: *** [src/CMakeFiles/inkscape_base.dir/build.make:2004: src/CMakeFiles/inkscape_base.dir/extension/internal/pdfinput/pdf-parser.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:2438: src/CMakeFiles/inkscape_base.dir/all] Error 2 make: *** [Makefile:156: all] Error 2 ```
