I'm new and trying to use Quazip under qt 5.5. So I just downloaded project sources from http://quazip.sourceforge.net/ and opened .pro file. When I try to build project I 've got multiple errors:
C1083: Cannot open include file: 'zlib.h': No such file or directory
To avoid building zlib on windows I just installed (from here: http://gnuwin32.sourceforge.net/packages/zlib.htm) complete pack for windows in C:\GnuWin32. Then I added this line in .pro file:
INCLUDEPATH += C:\GnuWin32\include
This generated another error:
Cannot open include file: 'unistd.h': No such file or directory
But changing this line
#if 1 /* HAVE_UNISTD_H -- this line is updated by ./configure */
into this fixed the problem.
#if HAVE_UNISTD_H
Unfortunately now I get 25 unresolved external symbols, some of them:
quaadler32.obj:-1: error: LNK2019: unresolved external symbol adler32 referenced in function "public: virtual unsigned int __cdecl QuaAdler32::calculate(class QByteArray const &)" (?calculate@QuaAdler32@@UEAAIAEBVQByteArray@@@Z)
quacrc32.obj:-1: error: LNK2019: unresolved external symbol crc32 referenced in function "public: virtual unsigned int __cdecl QuaCrc32::calculate(class QByteArray const &)" (?calculate@QuaCrc32@@UEAAIAEBVQByteArray@@@Z)

quaziodevice.obj:-1: error: LNK2019: unresolved external symbol deflateInit_ referenced in function "public: virtual bool __cdecl QuaZIODevice::open(class QFlags<enum QIODevice::OpenModeFlag>)" (?open@QuaZIODevice@@UEAA_NV?$QFlags@W4OpenModeFlag@QIODevice@@@@@Z)
quaziodevice.obj:-1: error: LNK2019: unresolved external symbol inflate referenced in function "protected: virtual __int64 __cdecl QuaZIODevice::readData(char *,__int64)" (?readData@QuaZIODevice@@MEAA_JPEAD_J@Z)
I tries adding this line:
LIBS += -LC:\GnuWin32\lib
But that didn't solve the problem. WHat is the easiest way to use Quazip under Qt?
