%X We study inclusive Λ<sub>c</sub><sup>±</sup>-baryon production in pp collisions in the general-mass variable-flavor number scheme and compare with data from the LHCb, ALICE and CMS collaborations. We perform a new fit of the c → Λ<sub>c</sub><sup>+</sup> fragmentation function combining e<sup>+</sup>e<sup>−</sup> data from OPAL and Belle. The agreement with LHC data is slightly worse compared with a calculation using an older fragmentation function, and the tension between different determinations of Λ<sub>c</sub><sup>±</sup> production cross sections from the LHC experimental collaborations is not resolved. The ratio of data for Λ<sub>c</sub><sup>+</sup>-baryon and D<sup>0</sup>-meson production seems to violate the universality of c-charm quark to c-hadron fragmentation.
