Setup query regarding Png++ install (unrelated to this repository) #17

Closed ShreyasSkandan closed 7 years ago

ShreyasSkandan commented 7 years ago

I'm trying to install Png++ with no sucess. I followed the instructions and tried to 'make' the installation.

This is my output from the first make command:

shreyas@shreyas:~/png++-0.2.9$ make make -C example make[1]: Entering directory /home/shreyas/png++-0.2.9/example' Makefile:45: pixel_generator.dep: No such file or directory g++ -M -Wall -I.. -I/usr/local/include -I/home/shreyas/anaconda2/include/libpng16 -g pixel_generator.cpp -o- | \ sed 's/\(pixel_generator\)\.o[ :]*/\1.o pixel_generator.dep : /g' > pixel_generator.dep make[1]: Leaving directory/home/shreyas/png++-0.2.9/example' make[1]: Entering directory /home/shreyas/png++-0.2.9/example' g++ -c -o pixel_generator.o pixel_generator.cpp -Wall -I.. -I/usr/local/include -I/home/shreyas/anaconda2/include/libpng16 -g g++ -o pixel_generator pixel_generator.o -L/usr/local/lib -L/home/shreyas/anaconda2/lib -lpng16 -g make[1]: Leaving directory/home/shreyas/png++-0.2.9/example'

And when I try to run make test, this is my ouput:

I'm hoping someone here knows how to fix this issue. I'm a bit lost. Any help is greatly appreciated.

FYI, this is what my test.log file looks like (154 errors)

Figured this one out!

Apparently libpng1.6 doesn't work well with Png++ version 0.2.9. I downgraded my libpng to version 1.2.50 and switched to the png++ 0.2.7 version and it works now.
