(I apologize in advance if this post isn't related closely enough to the topic of this group.)
I've been trying to modify some code that involves nsString variables. I'm having trouble just compiling the code.
I've chopped the C++ code down to just:
----------------------------------------------------- #include "nspr.h" #include "nsString.h"
main() { nsString aVendorName; } -----------------------------------------------------
and I'm trying to compile it with:
----------------------------------------------------- g++ \ -L/opt/SUNWics5/cal/bin \ -licsexp10 -lcsapi_xpcom10 -lmailwave -lmee -lcyrus \ -lyasr -lasync -lchartable \ -lnsres31 -lnsfmt31 -lnsuni31 -lnscnv31 -lnsbrk31 -lnscol31 \ -ladminutil -ldb26 -lldap40 -lnspr3 -lplds3 -lplc3 \ -I/opt/SUNWics5/cal/csapi/include \ -I/opt/SUNWics5/cal/csapi/include/include \ -R/opt/SUNWics5/cal/bin:/usr/local/lib \ -g t.cpp \ -Wno-deprecated -----------------------------------------------------
which returns:
----------------------------------------------------- Undefined first referenced symbol in file nsString::nsString[in-charge]() /var/tmp//ccsNzmyv.o nsString::~nsString [in-charge]() /var/tmp//ccsNzmyv.o ld: fatal: Symbol referencing errors. No output written to a.out collect2: ld returned 1 exit status -----------------------------------------------------
Does anyone happen to know what I'm doing wrong or how I'd debug this?
Thank you.
Eric

It looks like you need to link to the implementation of nsString. You can solve this problem in a number of ways. One simple solution is to link against libxpcom.so since it will contain the missing symbols. However, this will tie your application to that specific version of libxpcom.so since there is no guarantee that future versions of libxpcom.so will export the same symbols.
If you want a solution that works with future versions of Mozilla, then I suggest using nsEmbedString in place of nsString.
