Source code compiling/Makefiles/Compiling flags

This article or section is outdated and has not been fully updated to reflect the current version of SRB2. Please help the Wiki by correcting or removing any misinformation, as well as adding any new information to the page.

This is a list of flags that can be added when using the Makefiles method of compiling SRB2's source code, as of v2.2.8.

If it is appropriate to do so, these can be added as environment variables for your system, allowing you to omit the flags from the mingw32-make or make command to compile SRB2 with.

Platforms and interfaces

See also: Ports

These determine the platform or interface that SRB2's source code is compiled for. If none of these are given, by default SRB2 will be compiled for DOS using DJGPP, and the compiler will output srb2w16.exe to bin/Dos (object files will be sent to objs/djgppdos).

Note: List may include flags for ports that can no longer be compiled properly.

Variables

Unlike the flags in the previous sections, these are not simple on/off toggles but are variables that all take string values which determine options such as the names and paths of programs and tools to be used during compiling, compiler/linker flags for including libraries, and the name of the output executable.

Note that variables that specify a path can alternatively take the name of the program with no path, provided the program's path is already in your system's PATH environment variable.

For instance, when compiling on Windows, C:\MinGW\bin being in the PATH variable allows the following flag:

CC="C:\MinGW\bin\gcc.exe"

to be shortened to

CC=gcc

This works because gcc.exe is a file within C:\MinGW\bin, so the program can be specified directly instead of through its full path. However, this does not work if MinGW was installed in a different directory.

Compilers

Name	Description
CC=path	Determines the path for the program for compiling C programs; defaults to cc. For compiling SRB2 on Windows this should normally be set to gcc

Compiler flags (Main)

Name	Description

CPPFLAGS=flags	Extra flags to give to the C preprocessor and programs that use it
LDFLAGS=flags	Extra flags to give to compilers when they are supposed to invoke the linker
ASFLAGS=flags	Extra flags to give to the assembler. This is used for compiling vid_copy.o prerequisites vid_copy.s and asm_defs.inc

REMOVE=path_and_options	Determines the path and options for rm, the Unix program for removing objects such as files from the filesystem. Defaults to rm -f. Note: This program is used to remove the temporary file depend.ped during normal compiling, and by the clear target to remove all .o files in the corresponding objs folder. If rm is not available on the computer, both these actions will fail
MKDIR=path_and_options	Determines the path and options for mkdir, the Unix program for making new directories. Defaults to mkdir -p
GZIP=path	Determines the path for gzip. Defaults to gzip
GZIP_OPTS=options	Determines options for gzip. Default is -9 -f -n. Note: --rsyncable will be appended onto these options, whether the default options or custom options are used.
