Compiling error help please

[tonoftux]

So I am compiling a program that relys on some libraries. They are all installed. a ./configure runs through ok and creates the make files. However make comes up with this error and halts:




make[2]: Entering directory `/home/noob/Downloads/agent2d-3.1.0/src'

now in the readme it says you can set the directory for the library manually, so I try this and I get the same error. Does anyone possibly know what's going on here?

What version of g++ are you running? The error message indicates that you need to add the -fpermissive flag for the code that generated the error to succeed. Either that or you need to go into the code and initialize it yourself. I've had problems like this when building some kernel versions in that some uninitialized variables were being read before they had any value assigned to them. I had to go into the appropriate kernel modules and modify the source code appropriately. After a couple of kernel updates, the problem went away (fixed by the maintainers I suspect).

Thanks for your quick and helpful reply. ./configure CXXFLAGS="-fpermissive" fixed a very frustrating problem

Glad to hear I could help. My guess is that you are running a very recent version of the compiler suite, such as 4.6.1?

[tonoftux]

Yes sir, 4.6.1 indeed!

Going with the bleeding edge in technology (hardware or software) sometimes means that you too will bleed! Anyway, glad to help.
