Hi,
i want to compile helm[1] for Fedora 29, but i want to compile it against the zlib system library.
I changed the following in the source code:
# use system library zlib
rm -rf ./JUCE/modules/juce_core/zip/zlib/zlib.h
sed -i 's|#define JUCE_INCLUDE_ZLIB_CODE 1|#define JUCE_INCLUDE_ZLIB_CODE 0|' JUCE/modules/juce_core/juce_core.h
sed -i 's|#include "../../../juce_core/zip/zlib/zlib.h"|#include "zlib.h"|' JUCE/modules/juce_graphics/image_formats/pnglib/pngstruct.h
but the compilation fails with this errors:
../../../JUCE/modules/juce_graphics/native/juce_RenderingHelpers.h:1915:14: required from here
../../../JUCE/modules/juce_graphics/native/juce_RenderingHelpers.h:969:24: warning: 'void* memcpy(void*, const void*, size_t)' writing to an object of non-trivially copyable type 'class juce::PixelAlpha'; use copy-assignment or copy-initialization instead [-Wclass-memaccess]
memcpy (dest, src, (size_t) (width * srcStride));
