Bug #: 55971
Summary: Preprocessor macros with C++11 raw string literals
fail to compile
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: nachms+...@gmail.com
It does not seem possible to create a macro which contains a C++ raw string
literal, when it should be.
Example:
-----------------
#include <iostream>
#define CREATE_CLIENTS R"(CREATE TABLE "clients"(
"clientId" INTEGER PRIMARY KEY AUTOINCREMENT,
"clientName" VARCHAR(64) UNIQUE
))"
int main()
{
std::cout << CREATE_CLIENTS << std::endl;
return 0;
}
-----------------
g++ -W -Wall -o test test.cpp -std=c++11
test.cpp:3:24: error: unterminated raw string
test.cpp:6:3: warning: missing terminating " character [enabled by default]
test.cpp:6:1: error: missing terminating " character
test.cpp:10:3: error: stray ‘R’ in program
test.cpp:4:3: error: expected unqualified-id before string constant
On the other hand, clang seems to be able to handle it:
clang++ -W -Wall -o test test.cpp -std=c++11
./test
CREATE TABLE "clients"(
"clientId" INTEGER PRIMARY KEY AUTOINCREMENT,
"clientName" VARCHAR(64) UNIQUE
)
