37-39 are weird.
The writeFile() function in gpio_test.cpp has a bug which prevents the program to write the data to the gpio file. In line 107 the sprintf() function writes out chars (%c), but it should write ints (%d). This is the way that is done by the pcDuino people in their c_environment library. Here is the fixed writeFile():
103 void writeFile(int fileID, int value)
104 {
105 char buffer[4]; // A place to build our four-byte string.
106 memset((void *)buffer, 0, sizeof(buffer)); // clear the buffer out.
107 sprintf(buffer, "%d", value);
108 lseek(fileID, 0, SEEK_SET); // Make sure we're at the top of the file!
109 write(fileID, buffer, sizeof(buffer));
110 }
