Description Carlo 2019-01-30 09:33:48 UTC
I successfully emerge sci-electronics/gtkwave, 2018-04-11, with binutils-v2.29.1, gcc-v6.4.0

but now the same version of gtwave fails with gcc-v7.3.0, and the log says 

make[4]: Entering directory '/var/tmp/portage/sci-electronics/gtkwave-3.3.68/work/gtkwave-3.3.68/src/helpers'

I don't know if it's related or not, but I have recently created this demo to test 

#include <rpc/xdr.h>

int main(int argc, char *argv[])
    char buf[1024];
    XDR  x;
    int  n  = 5;
    char *s = "Hello, world.";

    xdrmem_create(&x, buf, 1024, XDR_ENCODE);
    printf("%d\n", xdr_getpos(&x));
    xdr_int(&x, &n);
    printf("%d\n", xdr_getpos(&x));
    xdr_wrapstring(&x, &s);
    printf("%d\n", xdr_getpos(&x));
    return 0;

gcc test.c -o test -ltirpc

it successfully compiles


ldd test => /lib/ (0xf8be4000) => /lib/ (0xf86de000) => /lib/ (0xf82ca000)
        /lib/ (0xf8ec9000)

so I am using /lib/, which belongs to net-libs/libtirpc-1.0.2-r1
Comment 1 Carlo 2019-01-30 10:49:47 UTC
not a good and elegant solution, but I have a workaround just to get gtkwave compiled again

ln -s /usr/lib/ /usr/lib/

now ./configure says 

checking for xdrmem_create in -lnsl... no
checking for xdrmem_create in -lrpc... yes

and emerge is happy 

2019-01-30 [ sci-electronics/gtkwave ] - success - @2.29.1/7.3.0

please, let me know if/how net-libs/libtirpc needs to be modified
Comment 2 Brian Evans (RETIRED) gentoo-dev 2019-01-31 14:31:43 UTC
Looks like configure isn't picking up net-libs/libnsl for these symbols
Comment 3 Carlo 2019-01-31 14:34:57 UTC
Indeed. weird.

I don't know why, but net-libs/libnsl is installed

Comment 4 David Seifert gentoo-dev 2020-10-03 16:20:35 UTC
Can you reproduce this with 3.3.106?
Comment 5 Agostino Sarubbo gentoo-dev 2023-01-23 09:28:52 UTC
usr-merge_tinderbox has reproduced this issue with version 3.3.111 - Updating summary.
Comment 6 Agostino Sarubbo gentoo-dev 2023-01-23 09:29:07 UTC
Dear treecleaner@:

usr-merge_tinderbox reproduced this issue right now.

Since it has not been fixed for a long time, I'd suggest to evaluate if it is the case to remove this package from the tree. Thanks
