Compiling and Linking Errors

If the C compiler issues an error message like the following:

cc: "myprog.c", line 16: error 1588: "FE_ALL_EXCEPT" undefined.

cc: "atanh.c", line 59: error 1588: "HUGE_VAL" undefined.

make sure your program includes the fenv.h and/or the math.h header file. If it does, make sure you are compiling with the default -Ae option or with both the -Aa and -D_HPUX_SOURCE options. See “Scalar Math Libraries (libm and libcl)” for details.

If the linker issues an error message like the following:

/usr/ccs/bin/ld: Unsatisfied symbols:
   log10 (code)
   sqrt (code)
   pow (code)

you may have forgotten to link in a math library (-lm). See “Scalar Math Libraries (libm and libcl)” for details. If the linker issues a similar message for a macro:

/usr/ccs/bin/ld: Unsatisfied symbols:
   isfinite (code)

make sure your program includes the math.h header file.

If the linker issues an error message like the following:

/usr/ccs/bin/ld: Illegal argument combination (/usr/lib/libm.a(cs_fabsf.o), fabsf)

make sure you are compiling with the default -Ae option or with both the -Aa and -D_HPUX_SOURCE options. See “Scalar Math Libraries (libm and libcl)” for details.
