Thanks for the report. The patch that introduced the shared library and the patch that split libspdk_thread out of libspdk_util did not get properly merged, so libspdk_thread was missing from libspdk.so. Please try with this patch: https://review.gerrithub.io/#/c/spdk/spdk/+/417171 Thanks, -- Daniel From: SPDK [mailto:spdk-bounces@lists.01.org] On Behalf Of Great Wizard Sent: Thursday, June 28, 2018 1:50 AM To: spdk(a)lists.01.org Subject: [SPDK] Shared Library Alone Doesn't Allow BlobFS Creation Hi. I saw a commit referencing the ability to build a shared library in SPDK now, stating "The combined library includes all components of SPDK and is intended to make linking against SPDK easier.". I tried to make a simple program initiating a (broken) blobfs, but at compilation time I'm required to link to -lspdk_thread to get it to build. #include "../../../include/spdk/blob.h" int main(int argc, char const *argv[]) { spdk_fs_init(NULL, NULL, NULL, NULL, NULL); return 0; } gcc test.c -o test -lspdk gives errors about undefined references to spdk_io_channel and thread functions. gcc test.c -o test -lspdk -lspdk_thread builds fine. Am I misunderstanding when I think of the shared library as a sort of "one library fits all" library that means I typically wouldn't need to link anything else? Thanks for your time.
