I have encountered this problem, you are just missing build dependencies, if you work on ubuntu, you need
sudo apt build-dep libxml2 libxslt libpng qemu wine
But in the end it is still the problem
#22

[ric96]

sudo apt build-dep libxml2 libxslt libpng qemu wine
that didn't help

[stefand]

The build deps should not be the issue in this case. Libxml and libxslt are compiled for the guest side (i.e., x86 and x86_64 windows) so that the guest side msxml.dll from Wine can link against it.

It seems that your libxslt does not find libxml. A few things to try:

*) Don't use a parallel make, i.e., run just "make" and not "make -j XX". Start with a clean hangover tree.
*) If that fails with the same error, build libxslt with V=1. Look for the libxslt dir in build/, cd into it and run "make V=1". It will give more details. Sorry, I don't have the exact name of the directory in my head.

my failed command was
/bin/bash ../libtool --silent --tag=CC --mode=link x86_64-w64-mingw32-gcc -I/home/eugene/hangover/build/x86_64-w64-mingw32/include/libxml2 -I/home/eugene/hangover/build/x86_64-w64-mingw32/include -g -O2 -Wall -Wformat=2 -Wmissing-format-attribute -version-info 8:20:8 -no-undefined -o libexslt.la -rpath /home/eugene/hangover/build/x86_64-w64-mingw32/lib exslt.lo common.lo crypto.lo math.lo sets.lo functions.lo strings.lo date.lo saxon.lo dynamic.lo ../libxslt/libxslt.la
I have added ../../libxml2_64/libxml2.la at the end to include libxml2 and apparently it fixed the build

[stefand]

It is not trying to link to libxml2. Is libxml2 built correctly?

[stefand]

Er, I did not read your last commend carefully enough. So libxml2 is there, although I think it should be built as a dynamic DLL, not a statically linked library. Something is certainly wrong - you shouldn't have to manually patch up build instructions...

[savelov]

so for building 64-bit libexslt.la I had to manually add ../../libxml2_64/libxml2.la to the cmd line, and for 32-bit libexslt.la - ../../libxml2_32/libxml2.la
apparently root Makefile need to be amended to include those libraries for linking

[stefand]

pkgconfig should figure this out. We invoke libxslt's configure with a PKG_CONFIG_PATH that points to the location where the Win32/Win64 build of libxml2.dll is placed.

Do you have pkgconfig installed on your system? If it is missing it might explain the symptom, although I would expect libxslt's configure to fail because it isn't able to find libxml2.

[savelov]

did you mean pkg-config? it is present, but I assume this is for system libraries - but as I am on aarch64, local aarch64 libxml2 will not help, as I need x86_64 one to link

[GrandBasis]

As stefand said, the libxml2 static library was not found during the link phase, but it has been built correctly. You need to add the $(LIBXML_LIBS) parameter to the /hangover/libxslt64/libexslt/Makefile 144 line libexslt_la_LINK variable. This parameter is in the Makefile. Already defined but not used, I don't know why, after the generated libxslt32 also has the same problem

[GrandBasis]

I tried to add $(LIBXML_LIBS) in the hangover/libxslt/libexslt/Makefile.am 30 line variable libexslt_la_LIBADD, the libexslt.la dependency library is included, and the compilation is successful, I don't know if there is any impact on other locations.
