| Description |
My program has some functions and procedures embedded in other functions and procedures embedded in other functions and procedures and I like to use long type names and descriptive function/procedure names and I think the linker likes to use names like function_name_one_inside_function_name_two_inside_function_name_three_with_argument1type_with_a_long_name_and_argument2_with_a_longer_name and I think this overwhelms the 255 character string making it impossible to distinguish one function from another since there is, in all probability, no string overflow range check in any case, if there were an abstraction in a table such as: LINKER NAME INSTEADOF "t1"programmer's type named "variablePointerToRecordNameBizzarrelyLongName" "t2"programmer's type named "variablePointerToRecordThatIsDifferentButLong" ... "f1"programmer joey's function named "reallylongname" It would be possible to rid the compiler of this bane that has prevented so many programmers from giving up w32010 which handles this quite nicely. -------------------------------------------------------------------- Another possibility is that this error indicates "too many literal strings" since w32010 chokes on that very thing. Strings such as the null string are given 256 characters if they are passed to a function expecting a string. Ironically, the null string need only take one byte since that is the length which is zero. LITERAL strings need only take the (number of bytes of their length + 1) since they do not change. The number of bytes may have to be rounded to an even byte number or even multiple of the natural 'int' for the machine type but guys, a byte saved can make all the difference! |

It is a known issue that FPC does not correctly deal with very long mangled names under certain circumstances. |
|
(0032526) Jonas Maebe (manager) 2009-11-27 16:41 |
Also, what is "w32010"? |
|
(0033426) Marco van de Voort (manager) 2010-01-01 23:46 |
1.0.10/win32 maybe? |
