In the binary_to_compressed.cpp file it says:

11 // Build with, e.g:
12 //    # cl.exe binary_to_compressed_c.cpp
13 //    # gcc binary_to_compressed_c.cpp

However, this is incorrect. Actually, you need to build with g++ since its a .cpp file. Otherwise, it tries to compile things a .c instead of .cpp, which of course produces errors...

$ gcc binary_to_compressed_c.cpp
/tmp/ccQbimqN.o: In function `binary_to_compressed_c(char const*, char const*, bool, bool)':
binary_to_compressed_c.cpp:(.text+0x299): undefined reference to `operator new[](unsigned long)'
binary_to_compressed_c.cpp:(.text+0x2e9): undefined reference to `operator delete[](void*)'
binary_to_compressed_c.cpp:(.text+0x348): undefined reference to `operator new[](unsigned long)'
binary_to_compressed_c.cpp:(.text+0x680): undefined reference to `operator delete[](void*)'
binary_to_compressed_c.cpp:(.text+0x699): undefined reference to `operator delete[](void*)'
collect2: error: ld returned 1 exit status

The correct way to build with gcc is:

$ g++ binary_to_compressed_c.cpp -o font2c
$ ./font2c
Syntax: ./font2c [-base85] [-nocompress] <inputfile> <symbolname>

You have to specify an output or else it outputs to a.out which is no fun...

Just thought you'd want to know... CHEERS!
