[R-pkg-devel] warning: explicit assigning values of variable of type ....

[Søren Højsgaard]

Dear all,

From CRAN maintainers I recieve:


Flavor: r-devel-linux-x86_64-debian-gcc
Check: whether package can be installed, Result: WARNING
  Found the following significant warnings:
    grips_fit_ips.cpp:149:45: warning: explicitly assigning value of variable of type 'int' to itself [-Wself-assign]
    grips_fit_ips.cpp:213:16: warning: explicitly assigning value of variable of type 'int' to itself [-Wself-assign]
    grips_fit_ips.cpp:254:10: warning: explicitly assigning value of variable of type 'int' to itself [-Wself-assign]
    grips_fit_ips.cpp:254:21: warning: explicitly assigning value of variable of type 'double' to itself [-Wself-assign]
 


The first warning pertains to the line:

    conips_inner_(S, K, elst0, clist0, print=print);

print on lhs of "=" is the formal name and print on rhs of "=" the name of a variable. Does the compiler think I assign an integer
to itself? Like if I write

int a=7;
a=a;

Can anyone help me throw light on this?

Thanks in advance
Søren
