the Linux® C++ compiler are available in the
bldapp
build script.
Compile and link options for bldapp
Compile
options:
g++
- The GNU/Linux C++ compiler.
$EXTRA_C_FLAGS
- Contains one of the following flags:
-m31
on Linux for zSeries only, to build a 32-bit library;-m32
on Linux for x86, x64 and POWER®, to build a 32-bit library;-m64
on Linux for zSeries, POWER, x64, to build a 64-bit library; or- No value on Linux for IA64, to build a 64-bit library.
-I$DB2PATH/include
- Specify the location of the Db2 include files.
-c
- Perform compile only; no link. This script file has separate compile and link steps.
Link options:
g++
- Use the compiler as a front end for the linker.
$EXTRA_C_FLAGS
- Contains one of the following flags:
-m31
on Linux for zSeries only, to build a 32-bit library;-m32
on Linux for x86, x64 and POWER, to build a 32-bit library;-m64
on Linux for zSeries, POWER, x64, to build a 64-bit library; or- No value on Linux for IA64, to build a 64-bit library.
-o $1
- Specify the executable.
$1.o
- Include the program object file.
utilemb.o
- If an embedded SQL program, include the embedded SQL utility object file for error checking.
utilapi.o
- If a non-embedded SQL program, include the Db2 API utility object file for error checking.
$EXTRA_LFLAG
- For 32-bit it contains the value "-Wl,-rpath,$DB2PATH/lib32", and for 64-bit it contains the value "-Wl,-rpath,$DB2PATH/lib64".
-L$DB2PATH/$LIB
- Specify the location of the Db2 static and shared
libraries at link-time. For example, for 32-bit:
$HOME/sqllib/lib32
, and for 64-bit:$HOME/sqllib/lib64
. -ldb2
- Link with the Db2 library.
