Neels Hofmeyr gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/1981 to look at the new patch set (#2). BTS: fix overloading ambiguity cast the result of rfn - m_cur_rfn to long int explicitly to avoid the overloading ambiguity between various abs() implementations for int, long int, long long int. Fixes opensuse builds for nightly packages, which had error: [ 110s] bts.cpp: In member function 'uint32_t BTS::rfn_to_fn(uint32_t)': [ 110s] bts.cpp:553:25: error: call of overloaded 'abs(uint32_t)' is ambiguous [ 110s] if (abs(rfn - m_cur_rfn) > RFN_THRESHOLD) { [ 110s] ^ [ 110s] In file included from /usr/include/c++/6/cstdlib:75:0, [ 110s] from /usr/include/c++/6/stdlib.h:36, [ 110s] from /usr/include/osmocom/core/linuxrbtree.h:97, [ 110s] from /usr/include/osmocom/core/timer.h:35, [ 110s] from ./bts.h:29, [ 110s] from bts.cpp:21: [ 110s] /usr/include/stdlib.h:735:12: note: candidate: int abs(int) [ 110s] extern int abs (int __x) __THROW __attribute__ ((__const__)) __wur; [ 110s] ^~~ [ 110s] In file included from /usr/include/c++/6/stdlib.h:36:0, [ 110s] from /usr/include/osmocom/core/linuxrbtree.h:97, [ 110s] from /usr/include/osmocom/core/timer.h:35, [ 110s] from ./bts.h:29, [ 110s] from bts.cpp:21: [ 110s] /usr/include/c++/6/cstdlib:185:3: note: candidate: __int128 std::abs(__int128) [ 110s] abs(__GLIBCXX_TYPE_INT_N_0 __x) { return __x >= 0 ? __x : -__x; } [ 110s] ^~~ [ 110s] /usr/include/c++/6/cstdlib:180:3: note: candidate: long long int std::abs(long long int) [ 110s] abs(long long __x) { return __builtin_llabs (__x); } [ 110s] ^~~ [ 110s] /usr/include/c++/6/cstdlib:172:3: note: candidate: long int std::abs(long int) [ 110s] abs(long __i) { return __builtin_labs(__i); } [ 110s] ^~~ Change-Id: I146dd82d9a18b1ad28749f960068d3b4e4cbfd9d --- M src/bts.cpp 1 file changed, 1 insertion(+), 1 deletion(-) git pull ssh://gerrit.osmocom.org:29418/osmo-pcu refs/changes/81/1981/2 diff --git a/src/bts.cpp b/src/bts.cpp index 548d000..75beaec 100644 --- a/src/bts.cpp +++ b/src/bts.cpp @@ -550,7 +550,7 @@ * number exceeds a certain limit, we need to assume that the incoming * rach request belongs to a the previous rfn period.
