Are you linking the MYTYPES.cpp file into
your build? If not, try this instead: g++ -lc++asn1 myApp.cpp MYTYPES.cpp Dave Abarbanel BAE Systems From: owner-imc-snacc@xxxxxxxxxxxx
[mailto:owner-imc-snacc@xxxxxxxxxxxx] On
Behalf Of Andrés Fuentes For example, I have a file named MYTYPES.asn1: MYTYPES DEFINITIONS ::= BEGIN dSalReq OBJECT-TYPE
SYNTAX DSalReq
ACCESS read-write
STATUS mandatory
::= 1001 dSalRes OBJECT-TYPE
SYNTAX DSalRes
ACCESS read-write
STATUS mandatory
::= 1002 Primary ::= SEQUENCE {
req [1] IMPLICIT INTEGER,
msgType [2] IMPLICIT INTEGER,
msg ANY DEFINED BY msgType } DSalReq ::= SEQUENCE {
subs [1] IMPLICIT MyId,
req [2] IMPLICIT Units,
min [3] IMPLICIT Units OPTIONAL,
apply [4] IMPLICIT NULL } DSalRes ::= SEQUENCE {
subs [1] IMPLICIT MyId,
bStat [2] IMPLICIT BStat } BStat ::= ENUMERATED {
max (0),
min (1),
credit (2),
zero (3) } MyId ::= OCTET STRING
(SIZE(5..20)) Units ::= INTEGER END I use esnacc like this:
esnacc -C -M MYTYPES.asn1
(or esnacc -C MYTYPES.asn1
produce the same result). and I obtain the MYTYPES.h and MYTYPES.cpp. Then I change
the include headers that correspond the correct directory. I write an application named myApp.cpp: #include
"MYTYPES.h" using namespace SNACC; int main(void){
char myBuffer[] = {0x31,0x32,0x33,0x34,0x35,0x36,0x37,0x38,0x39,0x31,0x32,0x33,0x34,0x35};
size_t sizeBuffer = sizeof(myBuffer);
MyId myId(myBuffer,sizeBuffer);
DSalReq myDis = DSalReq();
return 0; } When I compile it with the command:
g++ -lc++asn1 myApp.cpp I have the following result: /tmp/ccxcpWm4.o(.gnu.linkonce.t._ZN5SNACC4MyIdD1Ev+0xb):

exit status Excuse me if it’s an obviously
error, I’m new using esnacc and I don’t program very hard in c++.
Thank you for your help. Andrés

[mailto:owner-imc-snacc@xxxxxxxxxxxx] En nombre de Abarbanel, David (US SSA) I couldn’t reproduce this problem right off the bat,
but if you could provide a little more info that would be great. For instance, what parameters are you passing to the esnacc
executable when you compile the ASN.1 module? Also, if you were to
re-define the ASN.1 definition without a size (rather than commenting out the
SizeConstraint function), will it still give an error during your build? Regards, Dave Abarbanel BAE Systems From: owner-imc-snacc@xxxxxxxxxxxx
[mailto:owner-imc-snacc@xxxxxxxxxxxx] On Behalf Of Andrés Fuentes Please help me; I have a .asn1 file with the following types: McMsisdn ::= OCTET STRING
(SIZE(3..20)); I’m using eSNACC 1.7 with patch 1.7.4 with Red Hat
Enterprise Linux 4, g++ (GCC) 3.4.3 20041212 (Red Hat 3.4.3-9.EL4). I ran esnacc to obtain the .h and .cpp files. In another file
I wrote my application with the following calls:
char myBuffer[] =
{0x31,0x32,0x33,0x34,0x35,0x36,0x37,0x38,0x39,0x31,0x32,0x33,0x34,0x35};
size_t sizeBuffer = sizeof(myBuffer);
McMsisdn myMcMsisdn(myBuffer,sizeBuffer); When I compile it produces an error: /tmp/ccxwGq5g.o(.gnu.linkonce.t._ZN5SNACC8McMsisdnD1Ev+0xb):
In function `SNACC::McMsisdn::~McMsisdn()': : undefined reference to `vtable for
SNACC::McMsisdn' /tmp/ccxwGq5g.o(.gnu.linkonce.t._ZN5SNACC8McMsisdnC1EPKcj+0x1f):
In function `SNACC::McMsisdn::McMsisdn(char const*, unsigned int)': : undefined reference to `vtable for
SNACC::McMsisdn' collect2: ld returned 1 exit status I read a lot and tried to find the solution myself but in
the gcc documentation explain about virtual functions, etc. etc. I think that
is not the problem, I am not sure. The declaration of my class generated by esnacc is the
following /* OCTET STRING SIZE 3..20 */ class McMsisdn: public
AsnOcts {
public:
McMsisdn
():AsnOcts() { }
McMsisdn (const char *str):AsnOcts(str) { }
McMsisdn (const char *str, const size_t len):AsnOcts(str, len) { }
McMsisdn (const McMsisdn &o):AsnOcts(o){ }
const
SizeConstraint* SizeConstraints(int &sizeList)const;
McMsisdn
&operator = (const AsnOcts &o)
{ SetEqual(o); return *this;}
McMsisdn
&operator = (const char *str)
{ SetEqual(str); return *this; } }; When I comment the function “const
SizeConstraint* SizeConstraints(int &sizeList)const;” my application
compile fine, but I think that It is necessary to handle the maximum an minimum
size of the types. I don’t understand why this error. I need your help,
please. Andrés Fuentes |
