Are you talking about a linux build? If so, there's a section called "extra compiler flags"!

For instance (on Mac OS / Xcode) i have an Introjucer project with those sections:

1.&nbsp;"Extra compiler flags"

```
-Wall
-Wno-four-char-constants 
-Wno-unknown-pragmas
-Wshadow
-Wshorten-64-to-32
```

2. "Extra linker flags"

```
-F${C74SUPPORT}/max-includes
-framework MaxAPI
-bind_at_load
```

3. "Custom Xcode flags"

```
GCC_VERSION=4.2, WRAPPER_EXTENSION = mxo, GENERATE_PKGINFO_FILE = YES, GCC_SYMBOLS_PRIVATE_EXTERN = YES, PRODUCT_VERSION = 5.1.7, ARCHS = i386, DEPLOYMENT_LOCATION = YES, INSTALL_PATH = /, DSTROOT = "$(SRCROOT)/../../../../../sdk-build", DEPLOYMENT_POSTPROCESSING = YES, STRIP_INSTALLED_PRODUCT = YES, GCC_GENERATE_DEBUGGING_SYMBOLS = YES, GCC_DEBUGGING_SYMBOLS = full, DEAD_CODE_STRIPPING = YES, DEBUG_INFORMATION_FORMAT = dwarf-with-dsym, DWARF_DSYM_FILE_NAME = "$(PRODUCT_NAME).dSYM", DWARF_DSYM_FOLDER_PATH = "$(CONFIGURATION_BUILD_DIR)/$(EXECUTABLE_FOLDER_PATH)"
```
