Re: Suggestion for string to use in an Embedding XPCOM component

[Srinivasa Raghavan]

HI BDS, It just says ./run-mozilla.sh: line 131: 13768 Segmentation fault      "$prog" ${1+"$@"} Is there any way to get trace for it ? (I am in Linux Platform) By the way i am used GCC 4.0 while building the source,  and built the component in the same GCC it worked fine. But if i change the GCC to 3.2 to make compatible with other system which has GCC3.2, it crashes. Can you tell, the gcc can also be the cause for this problem i am facing.

Below is the libraries i am linking against with MOZILLA_INTERNAL_API defined, xpcom xpcom_core plds4 plc4 nspr4 This looks correct... did you get a stack trace for your crash? --BDS P.S. You don't need to send me private mail when you reply on the newsgroups.

Mainly I used nsString in my code and the functions I used are AppendWithConversion , AssignWithConversion ..etc. As there is more changes with respect to string in recent Firefox (Firefox 1.5) I need to change my implementation. As I used other Unfrozen interfaces apart from string in my code, which uses internal nsString classes, I need to define MOZILLA_INTERNAL_API. That's not necessarily true. If you're only using nonfrozen *interfaces* you don't need to define MOZILLA_INTERNAL_API... that define only affects *symbol linkage*. For what it's worth, it is almost never right to use the *WithConversion methods: they hardly ever handle character sets correctly. If you're converting from UTF8 to UTF16 use NS_ConvertUTF8toUTF16 and vice-versa. I tried string manipulation in a sample component with MOZILLA_INTERNAL_API defined.  I just declared nsString in a function, which causes firefox crash at runtime. Can anybody clear me why this crash happens ? What libs are you linking against? --BDS _______________________________________________ Mozilla-xpcom mailing list Mozilla-xpcom@mozilla.org http://mail.mozilla.org/listinfo/mozilla-xpcom
