Linking error when building txt2image in 5.0.0-alpha-546-g41c3 #2747

Closed oberw closed 5 years ago

Environment

5.0.0-alpha-546-g41c3 Linux nico 5.3.7-1-default #1 SMP Mon Oct 21 06:03:17 UTC 2019 (3eea5a9) x86_64 x86_64 x86_64 GNU/Linux

Current Behavior: Linking error for txt2image

[ 96%] Linking CXX executable ../../bin/text2image /usr/lib64/gcc/x86_64-suse-linux/9/../../../../x86_64-suse-linux/bin/ld: CMakeFiles/text2image.dir/pango_font_info.cpp.o: undefined reference to symbol 'g_free' /usr/lib64/gcc/x86_64-suse-linux/9/../../../../x86_64-suse-linux/bin/ld: /usr/lib64/libglib-2.0.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status [ 99%] Built target text2image Scanning dependencies of target mftraining

Expected Behavior: no error....

Suggested Fix: none, unfortunately, otherwise I would not have submitted this issue....

Posting just last part off error is useless. Please provide full information (from configuration, build system, system info)

What is OS version, pango version? cmake . does not work, but according your info it works ;-) Can you explain it please? What is output of pkg-config pango --libs and pkg-config pango --cflags? Can you try autotools build (which is the primary build system for linux system)?

Can you try autotools build (which is the primary build system for linux system)? ./configure fails, because there is no leptonica (1.74) pkg file, when you build libleptonica from source (opensuse does not provide a libleptonica-dev package)....

.....many ./configure checks deleted... checking for mbstate_t... yes checking for pkg-config... /usr/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking for libcurl... no checking for LEPTONICA... no configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

but cmake actually works (modulo the text2image build issue).

zdenop commented 5 years ago

It seems that your system is in your system or (at least) you have problem with installed of tesseract dependencies. I have experience with opensuse 15.1 and there is no problem to find leptonica with autotools. Correct installation of leptonica provides pc file for pkg-config.

Also your output of pkg-config pango --libs is problem (this output is used for tesseract build). My output on opensuse is -lpango-1.0 -lgobject-2.0 -lglib-2.0 (I got the same output on Raspberry pi which use debian), so you need to fix your pango installation.

Non of above mention problems can be fixed in tesseract.
