5 Known Problems and Workarounds
This section describes known problems and workarounds. Customers on support can
use the product number to assist them in finding SSB and SRB reports for HP aC++ or
HPC. The product number you can search for is B3910BA.
To verify the product number and version for your HP aC++ or HP C compiler, execute
the following HP-UX commands:
what /opt/aCC/bin/aCC
what /opt/aCC/lbin/ecom
Obsolete LANG-STARTUP Files
As of HP aC++ version A.06.15, the LANG-STARTUP fileset is obsoleted because its
only two files are no longer being delivered:
/opt/langtools/lib/hpux32/fastmem.o
/opt/langtools/lib/hpux32/effmem.o
codecvt_byname Facet Needed for C Locale Conversions
You must use the codecvt_byname facet to use C locale conversions.
To do locale-specific conversions, the codecvt_byname facet must be installed in the
locale:
typedef std::codecvt_byname<wchar_t, char, std::mbstate_t> ucs2utf;
locale default_locale(std::locale(), new ucs2utf("en_US.utf8"));
Using +check= Options and Running on Test and Deployment Systems
Using various +check= options requires a fairly recent version of wdb
(+check=malloc and +check=bounds:pointer) and
/opt/langtools/lib/hpux##/librtc.so.1 where the application is run. The
debugger and library is automatically updated on the machine only where the compiler
is installed. This may not be true where the application is executed.
Older versions of wdb may cause hangs. Older versions oflibrtc.so.1may produce
runtime unsats.
GPREL22 Relocation Error
If a variable is declared as extern non-array in one module and then defined as an array
in another, a linker error may occur:
Definition: foo.c:uint64_t variable[SIZE];
Reference: bar.c:extern uint64_t variable;
ld: The value 0xXXX does not fit when applying the relocation GPREL22 for
symbol "variable" at offset 0xYYY in section index ZZZ of file bar.o.
