The compile and link
options for building C embedded SQL and DB2® API
applications with the Linux C
compiler are available in the bldapp build script.
Compile and link options for bldapp
Compile
options:
- $CC
- The gcc or xlc_r 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:
- $CC
- The gcc or xlc_r compiler; 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
- Specify the 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.
